Comments

Ampicillin is a half-synthetic penicillin (β-lactam antibiotic), known to interfere with the wall peptide crosslinking in growing bacteria. It inhibits the enzyme activity of transpeptidase, carboxypeptidase and endopeptidase. Its action is bactericidal and the pH optimum for its action ranges from pH 5.5 - 6. At this pH value, its activity against E. coli is 10x higher in comparison to pH 8.Ampicillin sodium salt is readily watersoluble and stock solutions are prepared at concentrations of 50 mg/ml, stored at -20°C in aliquots. The working concentration in LB-ampicillin plates, LB or TB medium is 50 μg/ml (dilution 1 : 1000).Stability\: The activity of a 10 % aqueous solution of ampicillin, if stored at +4°C (pH 7), is reduced by 15 % after 24 hours, 33 % after 48 hours and 65 % after 7 days. At room temperature, the corresponding loss of activity is 28 %, 45 % and 81 %, respectively.
