Ampicillin Sodium Salt is a readily-soluble form of ampicillin. It belongs to the group of beta-lactam antibiotics. These antibotics gram-negative bacteria to which E. coli and Salmonella belong. beta-lactam antibiotic prevent the formation of peptidoglycan, an essential building block of the cell membrane. Thus, preventing growth of cells. Used to select for drug-resistant, plasmid-bearing bacteria.
