Cloning of A3C5 and Avi-Tag into pSB1C3

Investigator: NA, JH, CG

Aim of the experiment: Initial vector digestion was performed with NgoMiV and AgeI, producing complementary overhangs. Religated pSB1C3 (due to incomplete vector dephosphorylation) loses the AgeI recognition sequence. Therefore plasmids without insert should run in the supercoiled position at about 1.5 kb, plasmids with inserts should run in the linearised position at 3 kb. Single enzyme digestion was chosen, because the insert is too small to be solved on a gel.

Procedure:

analytic digestion: 3 µl of plasmid DNA P32 to P35 (about 300 ng) were digested with 0.3 µl AgeI-HF in 1 µl CutSmart Buffer and 5.7 µl H2O. The reaction was incubated for 2 h at 37°C.
5 µl digestion mix were loaded on a 1% agarose gel for electrophoresis, 1 kb ladder

Result:

P32 to P35 might carry the insert because they all appear in the linearized position at 3 kb
Therefore plasmid sequencing should confirm the result.

Lane 1: 1 kb ladder Lane 3: P32 Lane 4: P33 Lane 5: P34 Lane 6: P35

Polymerisation experiments for biotinylated eGFP and BSA with Streptavidin

Investigator: JH, CR, JB

Aim of the experiment: Determination of ideal concentrations for both protein interaction partners as well as buffer viscosity (glycerol content etc.) for polymerisation in a test tube

Procedure:

Different concentrations of proteins and glycerol were tested to support stable polymerisation without protein aggregates rising to the surface or sinking to quickly
The experiments done are not going to be further documented as the streptavidin used for the experiments was previously determined in a wrong fashion and was actually considerably lower than expected (4x lower). Streptavidin was, due to that circumstance, concentrated to be able to support experiments with at least 5 mg/ml concentrations
First experiments with concentrated streptavidin seemed promising, though a complete series of experiments with varying parameters should be conducted in the future

The next day, cultures were put into the fridge for storage until Monday.

Transformation of new E. coli XL1-blue (P75), additional plating of untransformated XL1-blue

Aim of experiment: Quality assurance

Investigator: Niklas

Procedure:

the new competent E. coli XL1-Blue cells were put out from the stock in -80 °C freezer and were gently thawed on ice.

1 µl of DNA was added to 50 µl of competent cells and gently mixed.

30 min incubation on ice

Adding of 950 µl LB-medium to each tube.

The cell suspension was plated on Cam-plates (inclusive rescue plate) and incubated over night at 37 °C.

additional plating of untransformated XL1-blue on Tet-, Cam-, Amp- and Kan-plates

Result:

After 12 hous of incubation there were some (~20) colonies on the 50µl-plate transformed with Cam-resistence-plasmids. The transformation has been succesful, though cells grow slow.
There were no colonies on the kan-, amp- and cam- plates with the untransformed E.Coli. Hence we can assume that there are no other plasmids with resistences against kan, amp or cam in our batch of competent cells.

There are cells on the tet-plate. This was expected.

"Blocking" Buffer: 1% BSA in PBS

Each well was covered with 0,5 ml BSA buffer and 0,5 ml bicarbonate buffer. After overnight incubation at RT, solution in wells was aspirated one by one and streptavidin was added. After a short incubation, the streptavidin(&Tris/HCl) solution was aspirated and Biotin solution was added (by needle).

SDS PAGE Streptavidin fermentation

Investigator: NA

Aim of the experiment: Verification of successfull production

Procedure:

according to protocol
8 µl Ladder; before induction; after induction
both samples: 3 µl culture + 77 µl TB + 20 µl SDS buffer; 12 µl on SDS gel

Results:

The fermentation was not successful, streptavidin band (unter 15 kDa marker) is just a bit thicker. The reason might be the ampR of the transformed plasmid. Due to the high cell concentration beta lactamase (secreted in periplasma) gets in the medium and hydrolyses amp. As a result cells lose plasmid because there is no selective pressure without an antibiotic in medium.

next step: cloning pf streptavidin mutants into pASK111 (camR)

Religated pSB1C3 (due to incomplete vector dephosphorylation) loses the AgeI recognition sequence. Therefore plasmids without insert should run in the supercoiled position at about 1.5 kb, plasmids with inserts  should run in the linearised position at 3 kb. Single enzyme digestion was chosen, because the insert is too small to be solved on a gel.
+'''Procedure:'''
+* analytic digestion: 3 µl of plasmid DNA P32 to P35 (about 300 ng) were digested with 0.3 µl AgeI-HF in 1 µl CutSmart Buffer and 5.7 µl H2O. The reaction was incubated for 2 h at 37°C.
+* 5 µl digestion mix were loaded on a 1% agarose gel for electrophoresis, 1 kb ladder
