Tests for ampicillin resistance given by protein added to mediumPiotr
-
Purification pACYC177+OmpA_alpha from antibiotic resistance contamination:
Inoculation of E. coli TOP10 carrying pACYC177+OmpA_alpha to liquid LB with kanamycin and with kanamycin and ampicillin.
- Inoculation of all pACYC177+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).
- Measurement of growth after 5 hours and on next day.
Cloning of protein A DNA to pET15b+OmpA-alpha plasmidAntoni
- Colony PCR on colonies from plates with transformations pGeneart+A Primers used:
AP+NotI and AL+SacI.
- Lack of confirmed transformant colonies.
Michał K.
- Isolation of plasmids from cultures inocluated on previous day (both potential constructs).
- Control
digest of isolated plasmids with FastBamHI and FastAcc65I (Fast Digest buffer).
- Gel electrophoresis - still no proper clones found.
