This beta-lactam antibiotic is an aminopenicillin. Like penicillin, it inhibits bacterial cell wall synthesis by preventing peptidoglycan cross-linking and murein assembly. The presence of an amino group confers greater efficacy against Gram-negative bacteria as compared to penicillin. Ampicillin is commonly used in molecular biology to assay for gene uptake (e.g., plasmid vectors carrying the ampicillin resistance gene).
