In order to check the expression of the proteins a single clone containing piGEM-019/-20 was used to inoculate 20 mL of LB-Can/Amp. The culture was incubated at 37°C until an OD of 0,7.

A 1 mL preinduction sample (PI) was taken (0,7 (favoured OD) : 0,7 (actual OD) = 1 mL). After that the cultures were induced with 20 µL IPTG for 2 hours.

An induction sample (I) was taken (320 µL with an OD of 2,2; 350 µL with an OD of 2).

PI and I were centrifuged at 14000 rpm for 1 min, the supernatant was discarded and the pellet resuspended in 60 µL water and 40 µL SDS-Buffer.

The four samples were analysed on an SDS-PAGE gel with 5 and 10 µL volume per sample.

The gel showed that the induction with IPTG was successful and the cells overproduce a protein after 2h incubation.

19.5 Protein overexpression with transformed E. coli BL21 (DE3)

20.13 First temperature shift

Aim: integration of pMAD-Insert into Bacillus chromosome via flanks

The 3 overnight cultures were used to inoculate 10 mL LB MLS until the culture obtained an OD of 0,1. The cultures were incubated at 30°C for 2h.

Then the temperature was shifted to 42°C for 6h.

After the heat shock 100 µL dilutions from 10^-4 to 10^-6 of each culture were plated out on MLS-X-Gal so that nine plates could be incubated overnight at 42°C.

19.7 Purification of Flagellin-Hag-SpeI from frozen pellet

The pellets which were stored at -80°C were resuspended in 20 mL buffer A and cracked with the microfluidizer. The cell lysate was centrifuged at 20000 rpm for 20 min at 4&degC. The supernatant was transferred to a new 50 mL falcon and stored on ice.

The following steps were performed:

equilibration with Buffer A 10 min
taking 40 µL supernatant (load)+ 10 µL SDS-Buffer - L-Sample
50 mL load on column
taking 40 µL of flow through + 10 µL SDS-buffer - FT-Sample
first washing with 25ml Buffer A (half the load)
taking 40 µL of washing flow through + 10 µL SDS-Buffer - W-Sample
equilibrate with Buffer B (output pipe off the column into glas, input into B)
hanging pipe on column, 6 x 2 ml Evolutions - E 1-6
taking 40 µL of Elution 1-6 + 10 µL SDS-Buffer E-sample 1-6

regeneration of column:

10min water
10min EDTA
10min water
10min NiSO4
10min water

Meanwhile the elutions 1-6 were pooled (combined 12 mL) in a 50 mL falcon and transferred in a concentrator column which was centrifuged until the volume in the filter was 1,5 mL for injection into the gel filtration station.

Parallel the L-, FL-, W- and E 1-6-samples were analysed via SDS-PAGE gel in order to proof the purification in the elution fractions.

The gel shows a huge protein concentration in E1 and E2 so that the purification could be continued with gel filtration. For that purpose the filtrate out of the concentrator was transferred into a new 2 mL tube resuspending very well without air bubbles.

17 mL of GeFi-buffer were injected into the loop. After that the protein filtrate was injected as well.

The GeFi was started according to the following settings:

Flow rate: 2500
max. pressure: 0,65 mPa
First endtimer at 90 mL volume before fractioning

After observing a peak on the screen 40 µL of different fractions (C7 , C9, C11, D1, D3, D5, D7) covering the peak were taken for analysis via SDS-PAGE gel.

The gel shows that the elutions contain the protein concentrated. The Elutions C7-D3 were pooled and transferred to the concentrator until an end volume of 200 µL.

The protein concentrate was used for crystallisation pure and in a 1:2 dilution with GeFi buffer.

Core I and II were used for setting drops.

13.69 new Gibson Assembly with mCherry I and II & linearized piGEM-002

Aim: recombination of piGEM-002 and mCherry

In order to receive the construct more piGEM-002 a different ration of the used parts was used for a new Gibson assembly.

From Insert I was a higher amount taken becaue of the bigger fragment size. New attempts with 1:2 (vector:insert) and 1:3 ration:

14.62 Transformation of BL21 cells

Aim: Transform E. coli BL21(DE3) with Arc1p-C-single-pET28a

40 µL E. coli BL21(DE3) electrocompetent cells were transformed with 1 ng of the previously purified plasmid Arc1p-C-single-pET28a from two different clones, incubated for 1 h at 37 °C and plated out on LB-Kan⁵⁰ plates that were incubated overnight at 37 °C.

19.9 Protein overexpression with transformed E. coli BL21 (DE3) (piGEM-021)

Aim: Overexpression of flagellin modifications for a second crystallization attempt

After freshly packed GeFi Columns we decided to purify the Fla-Cup again for crystallization.

For that purpose 2 x 1 L LB were inoculated with a solution of LB and every clone on the cotransformation plate. All clones from the piGEM-021 + FlaiS cotransformation plates were picked and resuspended in 1 mL LB. 500 µL were added to the 1 L culture flasks. Each flask was additionally mixed with 1 mL ampicillin (100 mg/ mL) and 1 mL canamycin (50 mg/ mL).

The expression was induced overnight with lactose (12,5 g/ L). 25 g lactose were solved in 100 mL millipore water which was heated 1 min in the microwave for solvation. Each culture was mixed with 50 mL of the lactose/ water suspension.

The cultures were incubated overnight at 30°C.

21.3 Expression of Flagellin

Aim: Check the expression of the modified flagella of Bacillus mutants

In order to check the expression of the flagellum in the Bacillus mutants cultures in 100 mL LB medium were grown until an OD of 0,8 at 37°C. 10 mL culture were centrifuged at 4000 rpm for 10 min to get the pellet. The pellet was resuspended in 60 µL water and 40 µl SDS-loading buffer. After that the sample was analysed via SDS-PAGE. Overexpressed E. coli flagellin was used as a positive control. The analysed samples should run on the same level as the ones produced in E. coli samples in case of a positive expression.

The gel showed that the Hag-SpeI mutant generates a band on the same level as the WT3610 which is a positive result because the modified flagellin with SpeI site has no remarkable change of molecule mass. The Bacillus transformation was successful though.

The mutants with the inserted Cup and DARPin showed no significant expression of the flagellin. Either the export of the flagellin is not possible for Bacillus because of the size/ folding of our constructs and ends in degradation of our modifications or the expression is too low to be analysed via SDS-PAGE. In that case it would not be efficient enough for further usage. The results of the SDS-PAGE fits to the previously made Swarming assays.

A new strategy had to be planned for further work.

14.63 Overnight culture

Aim: Inoculate Overnight culture of Arc1p-C-single-pET28a

5 mL of LB-Kan⁵⁰ medium were inoculated with a clone from 14.62 bearing the Arc1p-C-single-pET28a plasmid.

23.07.2014

14.64 Test Expression

Aim: Test the expression of Arc1p-C-single

Using the preculture from 14.63 60 mL of LB-Kan⁵⁰ medium were inoculated with 600 µL of the preculture and incubated at 37 °C and 220 rpm until OD₆₀₀ reached 0.5. The culture was cooled down to 18 °C and the protein production was induced with 12 µL of 500 mM IPTG. Over night the culture was incubated at 18 °C and 220 rpm. Afterwards the cell culture was centrifuged (17000 rpm, 20 min, 4 °C), the pellet resuspended in 3 mL buffer A and stored at -20 °C. A glycerolstock of the strain containing the Arc1p-C-single-pET28a plasmid was stored at -80 °C.

19.10 Purification of flagellin-Hag-Cup1-1 from frozen pellet

The pellets which were stored at -80°C were resuspended in 20 mL buffer A and cracked with the micro fluidizer. The cell parts were centrifuged at 20000 rpm for 20 min at 4°C. The supernatant was transferred to a new 50 mL falcon and stored on ice.

The following steps were performed:

equilibration with Buffer A 10 min
taking 40 µL supernatant (load)+ 10 µL SDS-Buffer - L-Sample
50 mL load on column
taking 40 µL of flow through + 10 µL SDS-buffer - FT-Sample
first washing with 25ml Buffer A (half the load)
taking 40 µL of washing flow through + 10 µL SDS-Buffer - W-Sample
equilibrate with Buffer B (output pipe off the column into glas, input into B)
hanging pipe on column, 6 x 2 ml elutions - E 1-6
taking 40 µL of elution 1-6 + 10 µL SDS-Buffer E-sample 1-6

regeneration of column:

10min water
10min EDTA
10min water
10min NiSO4
10min water

Meanwhile the Elutions 1 - 6 were pooled (combined 12 mL) in a 50 mL falcon and transferred into a concentrator column which was centrifuged until the volume in the filter was 1,5 mL for injection into the gel filtration station.

Parallel the L-, FL-, W- and E 1 - 6 -samples were analyzed on a SDS-PAGE in order to proof the purification in the elution fractions.

The gel shows a huge protein concentration in E1 and E2 so that the purification could be continued with gel filtration. For that purpose the filtrate out of the concentrator was transferred into a new 2 mL tube resuspending very well without air bubbles.

20 mL of GeFi-buffer were injected into the 2 mL loop. After that the protein filtrate was injected as well.

The GeFi was started according to the following settings:

Flow rate: 2500-3000 µL / min
max. pressure: 0,60 - 0,65 mPa
First endtimer at 80-90 mL volume before fractioning
Injectvalve

After observing a peak 40 µL of different fractions (C7 , C9, C11, D1, D3, D5, D7, D9) covering the peak were taken for analysis via SDS-PAGE.

The gel shows that the elutions contain the protein concentrated. The Elutions C7-D9 were pooled and transferred to a new concentrator until an end volume of 400 µL.

The concentrated protein had a pink color. The concentrated protein (38 mg/mL A280) was used for crystallization pure and in a 1:2 dilution with GeFi buffer.

Core I - IV were used for setting drops.

14.67 Purification of Arc1p-C-single

Aim: Purify Arc1p-C-single in three steps

The resuspended cells from 14.66 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-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 °C in aliquods for further use.
