Ampicillin differs from penicillin only by the presence of an amino group, which facilitates penetration through the outer membrane of some gram-negative bacteria. Ampicillin acts by interfering directly with the turnover of the bacteria cell wall and indirectly by triggering the release of enzymes that further alter the cell wall.

  • Used as selective antibiotic for resistant bacteria, generally at concentration of 10-25µg/ml for liquid media and 35-50µg/ml for plates
  • Product is provided as powder
  • Made into stock solution at 10mg/ml in water
  • Ampicillin is not used to prevent bacterial contamination of cell cultures due to concerns of mammalian and insect cell toxicity
