Gibco™ Ampicillin, Sodium Salt, Irradiated

Gibco Ampicillin is used as a selective antibiotic generally at a concentration of 20–125 µg/mL. Ampicillin selection is based on hydrolysis and inactivation of its beta-lactam ring by beta-lactamase expressed by the bla gene. Sometimes, beta-lactamase produced by the bacteria is secreted into the medium resulting in inactivation of ampicillin in the culture medium. Ampicillin degradation on agar plates can lead to the formation of satellite colonies. Growth of these colonies can be halted by adding fresh ampicillin. To avoid beta-lactamase buildup, special care must be taken while handling cultures and determining the correct dose of antibiotic.
