Tests for ampicillin resistance given by protein added to medium

Piotr

1. Purification Omp_alpha from antibiotic resistance contamination:
   Inoculation of E. coli TOP10 careing pACTC177+OmpA_alpha to liquid LB with kanamycin and with kanamycin and ampicillin.

2. Inoculation of all OmpA variants of constructs to LB + 0.25 mM IPTG, kanamycin, ampicillin (50 μg/ml) and 50 μg/ml of protein (Z_alpha and Z_omega; negative control without protein).
3. Measurement of growth after 5 hours and on next day.

Cloning of protein A DNA to pET15b+OmpA-alpha plasmid

Antoni

1. Colony PCR on colonies from plates with transformations pGeneart+A Primers used: AP+NotI and AL+SacI.
2. Lack of confirmed transformant colonies.

Cloning of alpha to pACYC177+OmpA_A_omega and pACYC177+OmpA_Z_omega

Michał K.

1. Isolation of plasmids from cultures inocluated on previous day (both potential constructs).
2. Control digest of isolated plasmids with FastBamHI and FastAcc65I (Fast Digest buffer).
3. Gel electrophoresis - still no proper clones founded.
