Tests for ampicillin resistance given by protein added to medium

Piotr

Inoculation of TOP10 carrying OmpA_A_alpha, OmpA_Adelta_alpha, OmpA_Adelta_omega, OmpA_A_omega, OmpA_omega_Adelta, OmpA_alpha, OmpA_omega and OmpA-omega-A-alpha to LB with inductor (0.25 mM IPTG) and kanamycin.

Cloning of protein A DNA to GeneArt plasmid

Antoni

1. Isolation of plasmids from bacterial cultures inoculated on previous day (pKS+A and pGeneart+Z).
2. Digest of pKS+A and pGeneart+Z with SacI and NotI (BamHI buffer), pGeneart dephosphorylation with CIAP.
3. Gel electrophoresis of digested plasmids and gel-out of proper bands (470 bp for protein A lane and 2570 for pGeneart)
4. Overnight ligation of pGeneart and A.

Cloning of alpha to pACYC177+OmpA_A_omega and pACYC177+OmpA_Z_omega

Michał K.

1. Clean-up of overnight digest reaction.
2. Ligation of digested vectors from 14 August and alpha DNA fragment.
3. Electroporation of E. coli TOP10 with ligations products.
4. Transformants plating on LB + kanamycine.
