Ampicillin Sodium Salt by MP Biomedicals is a high grade reagent. Ampicillin is a semi-synthetic antibiotic derivative of penicillin, active as a broad-spectrum antibiotic. This reagent is soluble in water, soluble in 1 M Ammonium Hydroxide, dilute acids or bases. It is practically insoluble in alcohol, chloroform, ether and fixed oils. It has a melting point of 215 C and the solution should not be autoclaved. CAS Number: 69-52-3 Quantity provided: 25 gm per bottle Molecular Formula: C16H18N3NaO4S Molecular weight: 371.39 pH: 8.0 - 10 Soluble in water: 50 mg/mLThis ampicillin sodium salt functions as an antibiotic and can be used in various industrial processes and for research. In molecular biology applications, these are used to select for ampicillin resistance in mutated and transformed cells. Ampicillin is used to treat infections by many Gram-positive and Gram-negative bacteria. It is a Penicillin derivative which inhibits bacterial cell-wall synthesis (peptidoglycan cross-linking) by inactivating the transpeptidases on the inner surface of the bacterial cell membrane. These may also be incorporated in media formulations for various fermentation processes. These antibiotics are suitable for microbiological research.
