18.50 Design of a Strep-Tag/ StrepDARPidin system

Aim: Designing a new system for using the Flagellin-DARPin-Konstrukt

A new plan was made to obtain the flagellas multi-functionality, using an affinity tag. We want to integrate a Strep-Tag into the flagellin so that the DARPin domain can be fused to the flagellum via streptavidin.

The D2 domain of Salmonella typhimurium's flagellin was used as a linker between the hag of Bacillus subtilis and the Strep-Tag, furthermore GSGS linkers were used between the D2 and the StrepTag.

Additionally the DARPin was designed with an N-terminal His-Tag and C-Terminal streptavidin, so a chimeric protein would be generated.

The designed structures were synthesized by Integrated DNA Technologies.

15.61 Design of Hag-D2-Cup

Aim: Designing a new domain construct for expression of cup1-1-Hag

We decided to design the flagellin as well with the D2 domain and the cup1-1.

The designed structures were synthesized by Integrated DNA Technologies

14.68 Crystallization of Arc1p-C

Aim: Crystallize the Arc1p-C-single domain

For the experiments the sitting drop method in SWISSCI MRC 2 well crystallization plates with a drop size of 1 µL was used (1:1 mixture of protein and crystallization solution) with an reservoir volume of 50 µL. Crystals of Arc1p-C-single were obtained by room temperature and at 6 mg/mL protein concentration after 1 week in 0.1 M MES, pH 6.0, 10% (v/v) glycerol, 30% (w/v) PEG 600 and 5% (w/v) PEG 1000. To collect data the crystals were flash frozen in liquid nitrogen and measured at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France at beamline ID23-1. The structure of Arc1p-C-single was determined by molecular replacement (MR) using the crystal structure of human Arc1p-C (PDB ID: 1FL0).

18.52 Isolation of flagella from Bacillus subtilis WT3610

Aim: isolation of filaments of WT3610 as negative control for e.g. FACS analysis & microscopy

The preculture was centrifuged at 4000 rpm for 15 minutes and the pellet was resuspended in 33 mL TRIS/HCl buffer (pH 8.0) with 0,5% Brij-58. A stock solution of lysozyme with 10 mg/mL was made. 330 µL were added to the TRIS/HCl buffer mix. The lysis was performed at 4°C while rotating the tubes until the pellet was completely solved which took approx. 2 - 3 hours. DNase (5 µg/ mL) in presence of 0,01 M magnesium chloride was added and incubated for half an hour at 4°C in the rotator as well.

After that the suspension was centrifuged at 10000x g for 10 min. 80 µL of the supernatant were transferred into a 1,5 mL tube. The supernatant was then centrifuged at 87000xg for 90min.

The pellet was resuspended in 10 mL standard saline citrate (0,01M trisodium citrate & 0,1M sodium chloride, pH 7,3) on ice and 80 µL were taken as well. For fractioning, 2 g of ammonium sulfate (20%) were added slowly until precipitation could be seen.

After some minutes of resting the suspension was centrifuged at 20000 rpm for 15 min. The pellet was then resuspended in 2 mL of standard saline citrate buffer. After taking a sample of 80 µL the 4 samples ware mixed with 20 µL SDS-loading buffer each and analysed on an SDS-PAGE.

The purified filaments were frozen in liquid nitrogen and then at -80°C.

The flagella purification was successful. Besides the flagellin the samples also contain the hook proteins, the smaller proteins were removed from the purified pellet.

14.69 tRNA^Phe assay

Aim: Measure aminoacylation levels

To measure aminoacylation of tRNA^Phe the components were mixed.

Content	Final concentration
Dialysis-buffer	ad 250 µL
DTT	1 mM
MgCl₂	20 mM
KCl	10 mM
tRNA^Phe	10 µM
L- or D-Phenylalanine	1 mM

After mixing, reaction was initiated by the addition of 2 mM ATP and then incubated for 1 to 60 min by 37 °C and 350 rpm. Assays were stopped by the addition of 25 µL 3 M sodium acetate solution. Afterwards tRNAs were precipitated with ethanol. Dissolved pellets were further purified using size-exclusion columns. The elution fraction was split into two aliquots. One samples was treated with 0.2 M NaOH (final concentration: 10 mM) and incubated at 50 °C for 10 min, while the other aliquot was kept on ice. The base treated sample was again acidified by the addition of 3 M sodium acetate (pH 5.2, final concentration: 300 mM). The volume of the untreated sample was adjusted using 2 mM sodium acetate (pH 5.2). Subsequently, both samples were subjected to LCMS analysis using 100 µL for injection.

25. Cell culture assays

25.1 Splitting of Caco-2-cells

Aim: Splitting cell culture for growing

The Caco-2-cells were kindly provided by Dr. Hartmann Reifert (BMFZ). In order to let them grow, the cells had to be splitted according to a specific protocol. Caco-2-cells require DMEM (Dulbecco’s Modified Eagle Medium) with 20% FCS and L-Glutamine.

A centrifuge was precooled to 4°C.

The medium of the culture flask was discarded from the side opposite to the adherent cells and washed with 1X PBS from the opposite site as well.

The PBS was aspirated with a glass pipette until the supernatant was clear. After adding 1 - 2 mL 1x trypsin from the opposite of the adherent cells the flask was incubated for 5 - 10 min at 37°C depending on how fast the cells unfastened of from the ground. Under the microscope the free floating cells were checked.

The cells were transferred into a 15 mL falcon and rinsed with 10 mL DMEM to collect all remaining cells in the flask. The 15 mL falcon was filled with DMEM and the culture centrifuged at 1500 rpm for 5 min at 4°C.

The supernatant was discarded and resuspended in 2 mL DMEM. The cells were splitted 1:3 which means that 666 µL were taken from the suspension and transferred into a new culture flask. After adding 20-25 mL DMEM the flask was incubated at 37°C and checked on the 3rd / 4th day under the microscope.

On the medium flask were the following notes:
Date, Name, Cell Line, Medium, Ratio of splitting, passage number

18.56 Expression-Test with transformed E. coli BL21(DE3)

Aim: Checking the overexpression of pET24d-StrepDARPidin

In order to check the expression of the proteins 5 clones (I6, II3, III3, III4, III6) containing piGEM-028 (pet24d-StrepDARPidin) were used to inoculate 20 mL of LB-Can. 5 cultures were incubated at 37°C until an OD of 0,7.

A ca. 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 2h.

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 10 µL volume per sample.

The gel did not show any signs of over expression so that lactose was chosen as an alternative inducer to test the expression. New test expression cultures (I6, II3, III3, III4, III6) were made with 100 mL LB-Can and 5 mL lactose (6,25 g/ 25 mL) per culture. Incubation was performed over night at 30°C.

18.57 His-bead purification of pellet from E. coli BL21(DE3)

Aim: Checking the overexpression of pET24d-StrepDARPidin

The 100 mL culture from I6 & III3 were centrifuged at 4000 rpm for 10 min in 2x50 mL falcons. The pellets were washed in 10 mL buffer A and cracked with the microfluidizer. After that the suspension was centrifuged at 20000 rpm for 20 min/ 4°C. The supernatant was transferred into a 50 mL falcon.

200 µL Ni-NTA beads were added to the suspension, inverted and incubated on ice for half an hour.

After that the suspension was centrifuged or 5 min at 4000 rpm so that the pellet could be resuspended in 500 µL Buffer A after discarding the supernatant. The 500 µL were transferred into a 1,5 mL tube and centrifuged at 4000 rpm for washing. After discarding the supernatant the pellet was washed again with 500 µL Buffer A. After a second centrifugation at 4000 rpm the supernatant was discarded, the pellet resuspended in 200 µL Buffer A and centrifuged at 13000 rpm to destroy the Ni-bead – protein interaction.

In the end the supernatant was transferred into a new 1,5 mL tube. The Ni-beads were mixed with 100 µL 20% ethanol.

40 µL of the supernatant from clone I6 and III3 were added with 10 µL SDS-PAGE Buffer and analysed on the SDS-Gel (visible at 18.56).
