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

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.

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).
