Tests for ampicillin resistance given by protein added to medium

Piotr

1. Inoculation of all OmpA variants of constructs to LB + 0.25 mM IPTG, kanamycin, ampicillin (50 μg/ml) and 100 μg/ml of protein (Z-alpha and Z-omega; negative control without protein).
2. Measurement of growth after 5 hours and on next day.

Cloning of protein A DNA to GeneArt plasmid

Antoni

Transformation of E. coli TOP10 strain with ligation products from previous day.

Cloning of alpha to pACYC177+OmpA_A_omega and pACYC177+OmpA_Z_omega

Michał K.

Colonies from both plates(pACYC177+OmpA_alpha_A_omega and pACYC177+OmpA_alpha_Z_omega) was inoculated to liquid LB with kanamycin (only two colonies grown on each plate).
