Ampicillin, sodium salt
AppliChem
Ampicillin is a half-synthetic penicillin (ß-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 to 6.
Ampicillin sodium salt is readily water soluble 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.
