Mutagenesis of protein A

Paweł

Mutagenesis of protein A was performed using 2 pairs of primers: ADelL+KpnI and ADelP (deletion of aminoacids involved in interaction with protein Z) and AMutL+KpnI and AMutP (changing of few aminoacids involved in interaction with protein Z).

Mutagenesis were performed on 3 vectors: pACYClac+ompA-A-omega, pACYClac+ompa-A-alpha and pACYClac+ ompa-alpha-A.

Each mutagenesis was performed using each primer at final concentration 0.1 μM, dNTPs at final concentration 0.25 μM and Walk (Pwo) polymerase (shipped by A&A Biotechnology), with 100 ng of DNA template.
