13.57 Mini Prep of cultures inoculated on Friday 30.05.14 containing the nose plasmids

piGEM010 = 22ng/µl
piGEM013 = 46 ng/µl
piGEM 009 = 13 ng/µl

low concentration: new transformation to obtain more plasmid DNA
Strain: new competent E. coli XL1-blue

15.50 Miniprep of pMAD-fla-cup1-1 for miniprep

The miniprep was performed according to the miniprep protocol.

Concentration 40 ng/µL
low concentration: new transformation to gain more plasmid DNA should be done
Strain: new competent E. coli XL1-blue

13.58 Bacillus Trafo with all Nose Plasmids containing one/no Degradation Tag

Aim: Create Bacillus subtilis strain 3610 containing the following plasmids: piGEM002 to 004 and piGEM007 to 016

Add 5µl plasmid DNA and incubate for 30 min at 37°C, LB plate with 5 ng/µL Cm (prepared freshly)

13.59 Inoculation of Bacillus subtilis wildtype (3610), gfp and silver nose

Aim: perform MTA to test the Ag concentrations where cells are still viable, since 1 mM until 10 µM were too high and the cells died

Starting from 1 mM, eight serial dilutions have been prepared

14.38 Purification of PheA-Arc1p-C-1x

Aim: Purify PheA-Arc1p-C-1x in three steps

The resuspended cells from 14.37 were lysed using a french press. The lysate was incubated on ice with 5 µg/mL DNAseA and RNAseI for 10 min and centrifuged (27000 rpm, 45 min, 4 °C) to pellet cell debris. The supernatant was filtered (0.45 µm) and PheA-Arc1p-C-1x purified from the cleared solution by NiNTA affinity chromatography. The combined elution fractions containing crude PheA-Arc1p-C-1x were concentrated to a volume of 2 mL and further purified using an anion exchange column to get rid of possible tRNA contaminations. Finally the buffer was changed to dialysis buffer and the protein concentrated and stored at -80 °C in aliquods for further use.

18.1 Tumor Terminator - Dilution of Plasmid

Aim: Creating a stock solution

We received the synthetized DARPin-gene in a pEC-A2 vector with SpeI restriction sites at the 5' - and 3' -site with an amount of 2,7 µg plasmid per tube.

A stock solution was created by adding 27 µl water to the tube.

Concentration of stock solution = 100 ng/µl

A 1:10 dilution was created by using 1 µl of stock solution adding 9µL of water to an end concentration of 10ng/µl.

Concentration of stock dilution = 10 ng/µl.

18.2 Transformation of E.coli XL1-Blue with pEX-A2-DARPin

Aim: Transformation of E.coli XL1-Blue with pEX-A2-DARPin for amplification of the plasmid.

1µl of the 1:10 dilution was used for transformation of E. Coli XL1-Blue

03.06.2014

18.3 Miniprep of pEX-A2-DARPin from E.coli XL1-Blue

Aim: Receiving a higher amount of plasmid for further experiments.

3 x 6ml LB-Amp were inoculated with clones from the successful transformed plate (18.2) and incubated at 37°C overnight.

13.60 Microtiter plate assay with wildtype, gfp strain 186 and silver nose

Aim: perform MTA to test the Ag concentrations where cells are still viable, since 1mM until 10 µM was too high and the cells died

Starting from 1 mM 8 dilutions have been prepared.
In the beginning Minimalmedium S750 has been prepared with 0.5‰ Xylose
In the wells the following mix was added to a total volume of 150 µl:
135µl of MM (90‰) and Silver solution (10‰)
15µl of cells
Finally 70 µl are added to avoid evaporation of the medium

Incubation for appr. 24 hours at 37°C shaking (Viktor AG Waldminghaus)

No positive GFP signal could be detected for the B. subtilis strain with the possible Ag sensitive promoter. The strain was restreaked onto a LB-Cm plate and he did not grow, which proved it to be a wrong strain, which has not been transformed successfully.

13.61 Checking Bacillus Trafo with all Nose Plasmids containing one/no Degradation Tag

Every transformation plate showed a huge growth of bacillus without single colonies. After one day of incubation this seems to be an unrealistic growth, which is why we planned to repeat the transformation after checking the growth of the Bacillus subtilis wildtype 3610 on LB-CM plate with 5 µg/ml chloramphenicol.

13.62 Checking Bacillus Trafo Wildtype 3610

Aim: check if wildtype has a resistance against chloramphenicol or if the plates are faulty

Bacillus subtilis Wildtype 3610 was plated on LB-chloramphenicol plate with 5 µg/ml chloramphenicol and incubated overnight at 37°C.

15.51 Making selection plates for clean deletions - integration of pMAD-construct into Bacillus subtilis chromosome

Aim: For the integration of the constructs we cloned into pMAD many steps of a special selection are necessary.

Antibiotics and chemicals:

Erythromycin 4 mg/ml
Lincomycin 25mg/ml
X-Gal 100mg/ml

For MLS selection plates erythromycin with 1 mg/ml were needed. Therefore the 4 mg/ml stock solution was diluted 1:4 by mixing 400 µl eryhtromycin with 1200 µl of 70% ethanol.

3 types of plates were made:

1. MLS selectin: 800 mL LB agar + 800 µl eryhtromycin + 800 µl lincomycin
2. MLS X-Gal: 800 mL LB agar + 800 µl eryhtromycin + 800 µl lincomycin + 800 µl X-Gal
3. X-Gal: 800 mL LB agar + 800 µL X-Gal

15.52 Sequencing of pMAD-fla-cup1-1

Aim: Checking the correct insertion of the metallothionein-domain into the hag-flank construct

Making a pre-mix for Eurofins MWG prepairing the sequencing. Primers from Florian Altegoer were used:

Flo83- Hag11_fw 1:10 with 1µl primer and 9µl water
Flo86- Hag12_rv 1:10 with 1µl primer and 9µl water

13.62 Checking Bacillus Trafo Wildtype 3610

Aim: check if wildtype has a resistance against chloramphenicol or if the plates are not effective/ made wrong

Result: Bacillus subtilis Wildtype 3610 grew on the chloramphenicol plate which shows us that there has to be a mistake in making the LB-chloramphenicol plates or the WT has a resistance.

New plates were made with new chloramphenicol-stocks with 25 mg/ml and 5 mg/ml.

3 aliquots of competent B.s. WT3610 were plated on new LB-chloramphenicol plates and incubated at 37°C.

18.5 SpeI restriction pEX-A2-DARPin & pMAD-hag-flank (piGEM-005)

Aim: Receiving iGEM-005 as linearized vector for cloning the DARPin gene with SpeI sites into pMAD-fla (iGEM-005)

Restriction	pEX-A2-DARPin digest (µl)	pMAD-Hag-Flank digest (µl)	Spe1-Mastermix

Incubation at 37°C for 2h and heat shock at 81°C for 5 min. After that the pMAD-hag-flank-construct was purified with the OMEGA gel extraction kit according to the protocol.

c(digested piGEM-005)= 4 ng/µl

13.62 Checking Bacillus Trafo Wildtype 3610

Aim: check if wildtype has a resistance against chloramphenicol or if the plates are not effective/ made wrong

Result: Bacillus subtilis Wildtype 3610 grew on the chloramphenicol plate. We have already repeated making plates so it might be that the WT has got a resistance while making it competent. A new WT was plated on 2 chloramphenicol plates with 5 µg/µL (old and new one) and 2x LB plates from gly stocks.

Incubation at 37°C overnight.

14.39 Creating PheA-Arc1p-C-0x

Aim: Using Round-the-horn mutagenesis to create PheA-Arc1p-C-0x-pET28a

The PCR with 5' phosphorylated TG_0xGSSG FP und TG_0xGSSG RP should generate the 7491 bp fragment for ligation from the methylated template PheA-Arc1p-C-8x-pET28a from 14.5.

The used Primer concentration was 1 µM, the concentration of the template was 1 ng/µL and we used a hot start to avoid unspecific annealing of primers.

10x CutSmart Buffer	3.6
Plasmid	30
DpnI	3
Total Volume	36.6

The reaction mixture was incubated at 37 °C and 300 rpm for 1 h and afterwards heated to 80 °C for 20 min.

In order to create the circular plasmid 100 ng of the linear template were mixed with 1 µL 10x T4-Ligasebuffer, 1 µL T4-Ligase and water to give a total volume of 10 µL. This mixture was incubated for 9 h at 16 °C. The resulting plasmid was dialysed with water to decrease the salt concentration for the following transformation of E. coli Top10 electrocompetent cells with the plasmid.

19. Crystallization of flagellin

In order to crystallize flagellin with a domain it is necessary to produce the protein by E. coli in a high concentration. For that aim the Fla-construct will be amplified out of pET24d which includes a domain. For elimination of the flanks a PCR has to be performed which just amplifies hag with domain and creates NcoI and BamHI restriction sites. After purification and digest with Nco/Bam the fragment can be ligated into digested pET24d . After transformation the production can be induced by IPTG.

19.1 Elimination of flanks from fla-construct including cup1-1 from pET24d

Aim: Preparation for using pET24d as expression vector for flagellin

The flagellin construct was amplified with specifically designed primers (95 and 54 from Florian Altegoer), which allow the amplification of the construct with cup1-1 without flanks (just Hag) including NcoI & BamHI restriction sites.
Template dilution 1:10:
1 µL pET24d-cup1-1 was mixed with 9 µL to an 1:10 dilution of 16,3 ng/µL
Primer dilution 1:10:
The primers were diluted 1:10 by mixing 10 µL of primers with 90 µL millipore water each.

The PCR was run over night.

19.2 Restriction digest of pET24d with NcoI and BamHI

Aim: Creating Nco/Bam restriction sites in pET24d for cloning PCR fragments amplified with primers flo56 and flo54 which contain these sites as well.

Isolated pET24d was cut with NcoI and BamHI in order to create restriction sites for ligating the Flagellin/ Hag-Domain fragments into the vector. The Hag-fragments which were amplified via PCR with primers flo54 and 56 contain NcoI/ BamHI restriction sites for that purpose as well.

pET24d (148 ng/µL)	7
CutSmart 10x	2
NcoI	0,5
BamHI	0,5
Water	10
Total Volume	20

Incubation for 1 hour at 37°C and heat shocked at 80°C.

15.52 Miniprep of different plasmids

Aim: Receiving more plasmid DNA for further experiments

Colonies were picked from plates and 8ml LB with necessary antibiotics each inoculated, followed by incubation at 37°C overnight.

Clones were picked from plates with plasmids:

pET24d-Fla-Cup1-1 (piGEM-006)
pMAD-Hag-Flank (piGEM-005)
pMAD-Hag-Flank -Cup1-1 (piGEM-016)
pEX-A2+DARPin (piGEM-017)

07.062014

15.53 Sequencing pMAD-fla-cup1-1

The sequencing showed the correct insertion of the cup-1-1 gene into the hag-flank construct but contained a stop codon, which was not removed by the used reverse primer. Unfortunately we used primers for amplification of the whole cup1-1 gene and not just for the truncated gene coding for the metallothionein domain only. Therefore new primers had to be designed an the Gibson assembly for integration of the metallothionein domain into pMAD and pET24d has to be repeated.

18.6 gel extraction & purification of DARPin gene

Aim: Receiving DARPin gene with SpeI sites for ligation into linearized piGEM-005

The with SpeI digested pEX-A2 was purified via electrophoresis with an 1% agarose gel in order to divide pEX-A2 backbone and the DARPin gene (489 bp). The digest attempt was splitted and loaded into two pockets to be sure not to overload the gel. The correct bands were cut out and the DNA fragment was rescued according to the protocol of our OMEGA gel extraction kit.

Expected bands:
DARPin gene: 489 bp
pEX-A2 backbone: 1961bp
The concentration after gel extraction: 9 ng/µl

18.7 Ligation of DARPin gene and linearized piGEM-005

Aim: Ligation of DARPin- (from 18.6) into Spe1 digested piGEM-005 from 18.5 for integration of the DARPin-Flagellin construct into Bacillus subtilis chromosome

The DARPin gene with SpeI sites was used as insert for the ligation into linearized pMAD (from 18.5) which contains the designed restriction site. The ligation attempt was done twofold and calculated by the Ligation Calculator from the iGEM-Team Texas in 2011:

Component	Volume [µl]
Insert (DARPin, c= 9 ng/µL)	2
Vector (piGEM-005, c=4ng/µL)	10
Ligase-Buffer 10x	2
T4 Ligase	1

Total Volume	20

Incubation was performed overnight at room temperature.

13.63 checking Bacillus WT 3610 growth on 5µg/µL CM

Aim: check if wildtype has a resistance against chloramphenicol (CM)

Result: Bacillus subtilis Wildtype 3610 grew on the CM plate.

In order to make out if a selection is possible WT3610 was plated out from an LB plate (13.62) on 25 ng/ µL CM to check were the threshold of CM for B. subtilis is.

Incubation at 30°C over two days.

08.06.2014

18.8 new SpeI restriction of DARPin-gene in pEX-A2 & pMAD-hag-flank (piGEM-005)

Aim: Receiving new insert and vector in case of an unsuccessful ligation for further attempts.

Restriction	pEX-A2-DARPin digest (µl)	pMAD-Hag-Flank digest (µl)	SpeI-Mastermix

Incubation was performed for 2 h at 37°C and heat inactivated at 80°C for 5 minutes.

18.9 Transformation of ligation from 18.7

The whole 20µL attempt from the ligations were used to transform E.Coli XL1-Blue, which were plated on LB-Amp plates. Additionally a negative control was created by transforming E.Coli XL1-Blue with 1 µL SpeI cut piGEM-005 as well.

18.10 Gel extraction for isolation of DARPin gene out of pEX-A2

Aim: Receiving new insert in case of an unsuccessful ligation for further attempts like in 18.6

The SpeI digested pEX-A2 was purified via electrophoresis with an 1% agarose gel like in 18.6. The correct bands were cut out and the DNA fragment was purified according to the protocol of our OMEGA gel extraction kit.

Expected bands:
DARPin gene: 489 bp
pEX-A2 backbone: 1961bp
The concentration after gel extraction: 10 ng/µl

18.13 Checking success of ligation via cPCR

Aim: A cPCR with the primers 54 and 56 shows the success of ligation by amplification of the Hag-construct.

In order to check the positive insertion of the DARPin gene into pMAD a PCR amplification with primers 54 and 56 for the flagellin should generate an ca. 1500 bp fragment on the gel. Negative clones would just show a 1000 bp band because of the amplification of the Hag-SpeI site construct. The picked clones were transferred on a new LB-amp plate.

Expected bands:
Hag-DARPin-construct: ca. 1500 bp

The gel shows bands at 1000 which means that the clones contain just relegated pMAD vector and are all negative. The ligation had to be repeated.

18.14 Dephosphorylation of linearized piGEM-005

Aim: Dephosphorylation of 5'-end with antarctic phosphatase in order to decrease the religation of the linearized piGEM-005 from 18.8

The cut SpeI cut piGEM-005 was dephosporylated at the 5'-end with antarctic phosphatase to prevent the vector from relegation.

18. new ligation of linearized/ dephosphorylized piGEM-005 & DARPin gene

Aim: Dephosphorylation piGEM-005 was ligated with extracted DARPin gene again

Because of the negative colony PCR from 18.13 a new ligation with dephosphorylized piGEM-005 from 18.14 and new extracted DARPin gene from 18.10 was performed in 2 attempts.

Component	Volume [µl]

Incubation 3h at room temperature

18.16 Transformation of overnight ligation from 18.15

The whole 20 µL reaction of the ligations (18.15) were used to transform E. coli XL1-Blue and plated on LB-Amp plates. Additionally a negative control was created by transforming E.Coli XL1-Blue with 1µL SpeI digested piGEM-005 as well.

13.64 checking Bacillus WT 3610 growth on 5, 10 & 15 µg/µL CM

Aim: check if wildtype has a resistance against CM

Result: Bacillus subtilis Wildtype 3610 did not grow on the 25 ng/µl CM plate

In order to check at which concentration CM Bacillus cannot survive he was plated out from an LB plate on LB-CM plates with different CM concentrations (5, 10, 15 ng/mL).

Incubation at 30°C over night.

10.06.2014

18.17 Checking Transformation of ligation from 18.16

Plate	Amount of colonies

Ligation attempt 1	2
Ligation attempt 2	>80

18.18 Checking success of ligation via cPCR

Aim: A cPCR with the primers 54 and 56 shows the success of ligation by amplification of the Hag-construct.

In order to check the positive insertion of the DARPin gene into pMAD a PCR amplification with primers 54 and 56 for the flagellin should generate an ca. 1500 bp fragment on the gel. Negative clones would show still just a 1000 bp band because of the amplification of the Hag-Spe1 site construct. The picked clones were transferred on a new LB-amp plate. 12 clones were picked.

Clone 1, 2, 3, 4, 5, 7, 9, 11 and 12 were the positive clones at 1500 bp.

14.40 Overnight culture

Aim: Amplify Plasmid in an overnight culture

Six clones of the transformed E. coli Top10 cells from 14.39 were picked and used to inoculate overnight cultures (6 x 5 mL).

18.19 Miniprep of positive clones

Aim: In order to check the orientation of the insert in the vector of the positive clones minipreps were inoculated for further experiments

Because of the ligation via two SpeI sites, the chance is 50:50 that the clones contain the pMAD-Hag-Flank-DARPin construct in the right orientation (Startcodon on the Hag1-site). For test digests a higher amount of plasmid is needed, which is achieved by inoculation of minipreps.

The clones were used to inoculate 7 mL LB-Amp and incubated at 37°C over night.

13.64 checking Bacillus subtilis WT 3610 growth on 25 & 35 µg/µL CM

Aim: check if wildtype has a resistance against CM

Result: Bacillus subtilis Wildtype 3610 grew on the 5, 10 & 15µg/µl LB-CM plate.

We saw that the Bacillus grew on almost every CM concentrations except 25 µg/µL. So we transformed competent WT3610 with Nose plasmid piGEM-003 as a positive control and plated them out on LB-CM with 25 µg/µL and 35 µg/µL.

Additionally, competent wildtype 3610 cells were transformed with piGEM-004 and plated out on LB-CM with 5, 10 and 15 µg/mL CM to check, if these cells can be selected better.

Incubation at 30°C for 2 days.

18.19 Miniprep of positive clones

The concentration of the isolated plasmids was between 100 and 150 ng/µL.

18.20 Test digest with EcoRV

Aim: Checking the right orientation of the insert in the isolated plasmids

The plasmids from the positive clones were digested with EcoRV so that specific fragments emerge when cutting into the DARPin gene and the vector backbone.

20.1 inoculation of preculture from Bacillus subtilis WT 3610

Aim: Preparation of for mainculture the next day

2 x 6 mL of LB were inoculated with Bacillus subtilis WT3610 from an LB plate and incubated at 37°C overnight.

14.41 Preparation of plasmids

Aim: Purify the amplified plasmids from overnight cultures

The plasmids were purified from the overnight cultures created in 14.40 using Sigma GenElute Plasmid Miniprep Kit following the included protocol. The plasmids were eluted using 45 µL water.

12.06.2014

18.21 PCR with pMAD-Hag-Flank-DARPin (piGEM-019) and piGEM-005

Aim: Amplification of Hag-SpeI-construct and Hag-DARPin construct with NcoI/BamHI sites for cloning into pET24d → crystallization of domains.

The templates (piGEM-005, prepped pasmid from clone 7 & 12 ) were diluted 1:10. piGEM-005 should function as a negative control. Clone 12 was picked in case the second orientation could be used for different experiments. 5 µL PCR product + 1 µL loading dye were analysed on an 1% agarose gel.

14.45 Purification of test expression

Aim: Purify PheA-Arc1p-C-0x on a small scale

Lysozyme was added to the cell suspension from 14.44 to a final concentration of 1 mg/mL and incubated on ice for 30 min. Afterwards the cells were lysed using ultra sound (2x 18 pulses, 30 s on ice inbetween). To clear the suspension of cell debris it was centrifuged (13000 rpm, 15 min, 4 °C). The supernatant was purified using QIAGEN Ni-NTA Spin Columns. An SDS-PAGE gel showed that the protein is produced and can be purified using Ni affinity chromatography.

60 mL LB-Kan⁵⁰ medium was inoculated from the glycerolstock prepared in 14.44 and incubated at 37 °C and 220 rpm over night.

18.37 Repetition of PCR with 3 clones of pET24d-Hag and pET24d-Hag-DARPin ligation

Aim: checking picked clones for correct Hag/ Hag-DARPin insert in pET24d

Gel electrophoresis:

The gel shows negative bands in case of the Hag-DARPin clones. The PCR for Hag 8 and 9 did not work although we cooked the clones in PBS. The transformation efficiency seemed to be very low, so clones from the new ligation attempts should be analysed.

18.38 Ligation checking success of transformed ligation attempts

On every plate grew a high amount of colonies. 6 clones of each plate were picked for inoculation of minipreps and for cPCR after cooking with PBS. The clones were transferred to another LB-Can plate.

18.39 cPCR with picked clones from 18.38 ligation attempt transformation

Aim: checking picked clones for correct Hag/ Hag-DARPin insert in pET24d

For checking the insertion of the Hag/-DARPin into pET24d the clones from the transformation plate were transferred to another LB-Can plate and cooked for 10 min in 30 µL PBS at 95°C. At the same time the colonies were used to inoculate LB-Can for minipreps.

18.39 Gel cPCR with picked clones from 18.38 ligation attempt transformation

Aim: checking picked clones for correct Hag/ Hag-DARPin insert in pET24d

Gel electrophoresis: no bands except for the controls were seen. The PCR has to be repeated with more colony in the PCR tubes or the prepped plasmids

18.40 Test digest with NcoI/BamHI of isolated plasmids from picked colonies

Aim: checking picked clones for correct Hag/ Hag-DARPin insert in pET24d

The picked clones from the ligation attempts 18.38 were isolated. In order to check the insertion of the Hag/ Hag-DARPin domain the plasmids were digested with NcoI/BamHI so that the gel should show the insert of 1 or 1,5 bp length and the pET24d backbone at 5300 bp. Because of an unavailable marker as a control the PCR amplified inserts which were used for the ligation will run with the gel as well. piGEM-001 will also be cut NcoI/BamHI in order to receive a marker band for the pET24d backbone.

18.41 New ligation of pET24d and PCR Hag/ Hag-DARPin fragments cut NcoI/BamHI transformation

Aim: ligation of construct with pET24d for overproduction of flagellin and crystallization

The cut pET24d NcoI/BamHI which was used for the previous ligations was not purified and contained an 1 kb insert. For a new clean ligation the reaction was repeated with digested pET24d. The NcoI/BamHI digested flagellin PCR products (from clone 7 and piGEM-005) were ligated with NcoI/BamHI digested pET24d.

The reactions were carried out in double and were incubated 1h at room temperature. Finally they were used to transform E. coli XL1-Blue after inactivation at 65°C for 10 min. The attempts 1.1 and 2.1 were incubated over night at room temperature. 1 µL of digested vector was used for a transformation as a negative control in order to check the amount of religants.

The ligation between pET24d and the Hag-/Hag-DARPin fragments which were both cut NcoI/BamHI was successful. The ligation plates showed over 20 clones each. However, on the negative control grew a few clones as well, which were very small and sticking together. In order to analyse the insert of the clones, 5 clones per ligation plate 1 and 2 were used to inoculate minipreps in 5 mL LB-Can. For the Ligation 1 pET-Hag clones 1-5 were picked, as well as clones 6-10 from Plate Ligation 2 pET-Hag-DARPin.

The cultures were inoculated over night at 37°C.

The supernatant was filtered (0.45 &micro;m) and PheA-Arc1p-C-0x purified from the cleared solution by NiNTA affinity chromatography. The combined elution fractions containing crude PheA-Arc1p-C-0x were concentrated to a volume of 2 mL and further purified using an anion exchange column to get rid of possible tRNA contaminations. Finally the buffer was changed to dialysis buffer and the protein concentrated and stored at -80 &deg;C in aliquods for further use.</p>
