1. Isolation of plasmids from cultures inocluated on previous day.
2. Control digest of isolated plasmids with BamHI and SacI (we confirmed 4 colonies but A in our constructs turned out to be trunctated and contain only one from two highly similar domains).

Cloning of omega_A DNA fragment to pACYC177+OmpA_alpha

Michał K.

1. DNA fragment of omega_A isolated from gel on 20 July digestion with SacI and NotI.
2. clean-upClean-up of digested DNA fragment.
3. Digestion (SacI and NotI) and dephosphorylation (CIAP) of pACYC177+OmpA_alpha.
4. Gel electrophoresis and gel-out of 4300 bp band.
5. Ligation of DNA fragments from 2. and 4. (1 hr)
6. Transformation of E. coli TOP10 strain with ligation.
7. Transformants plating on LB + kanamycin.

Checking if OmpA_omega_A_alpha gives ampicillin resistance
Piotr

Inoculation OmpA_omega_A_alpha from various IPTG concentrations (in mmol/mL) (0, 0.1, 0.25, 0.5, 0.75, 1) into same IPTG concentrations, but with various ampicillin concentrations (in mmol/mL)(25, 50, 75, 100) in ratio: 1:50.

Inoculation of OmpA_omega_A_alpha into various IPTG concentrations: 0, 0.1, 0.25, 0.5, 0.75 mmol/mL (replication is necessary)
