Main purpose

Who was in the lab

Kristian, Gosia, Julia, Henrike

Procedure

PCR for SPL and Ref (reference promoter)

template: pZa21 with RFP;

primers for SLP: 52a, 52b1; primers for Ref: 52a, 52b2;

temperature: 53C, time: 3:00;

Samples:

1 -> SLP + DMSO

2 -> SLP + betaine

3 -> Ref + DSMO

4 -> Ref + betaine

5 -> SLP Negative control + DMSO

6 -> Ref Negative control + betaine

PCR for AMO with USER endings

Midiprep

Purifying plasmids with high yield for sequencing of the samples cycAX, Sec2, TAT2-1, TAT3-2 and TAT3-1a.

Gel purification

Extracted from gel and purified AMO extraction fragment, araBAD promoter, Nir2 extraction fragment.

USER reaction

Performed USER ligation on araBAD inducible promoter and pZA21 without native promoter containing GFP Sf respective RFP following the standard protocol (I assume).

Results

Gel on yesterdays PCR

ara, SPL is from yesterdays PCR with 5% DMSO, Nir and the sample numbers is also from yesterday, here the composition can be seen.

not on the gel: 11 - Nir2, extraction PCR, primers 42a, 42b, cells in water, plus MgCl2 additive, Phusion polymerase

Decided to purify ara and Nir2 (from 12, 7, 8, 9 and 10) and analyse sample 11 (Nir2).
