The ampicillin resistance gene (AmpR) is called a selectable marker gene and is incorporated into several plasmids that are commonly used in a wide range of genetic engineering and molecular biology experiments.
Ampicillin is in the penicillin group of beta-lactam antibiotics and is part of the aminopenicillin family. It is roughly equivalent to amoxicillin in terms of activity.However it can be injected unlike amoxicillin and has lower oral bioavailability compared to amoxicillin.mpicillin acts as an irreversible inhibitor of the enzyme transpeptidase, which is needed by bacteria to make their cell walls. It inhibits the third and final stage of bacterial cell wall synthesis in binary fission, which ultimately leads to cell lysis; therefore ampicillin is usually bacteriocidal.
