Ampicillin is a broad-spectrum, beta-lactam antibiotic that belongs to the penicillin group. Ampicillin trihydrate is commonly employed in molecular biology techniques, such as bacterial culture studies and cloning experiments.

Ampicillin interferes with bacterial cell wall synthesis, leading to cell lysis and inhibiting bacterial growth. It is frequently used in the preparation of selective media for the cultivation of bacteria harboring ampicillin resistance genes.

Researchers use ampicillin as a tool to maintain sterile conditions in bacterial cultures and to selectively culture bacteria that have been genetically engineered to resist the antibiotic. This is particularly useful in molecular cloning experiments, where the presence of ampicillin helps select for the successful incorporation of plasmids carrying ampicillin resistance genes.
