Biochem/physiol Actions: Carbenicillin is an ampicillin analog with structure related to benzyl penicillin. It is effective against Gram-negative bacteria and exhibits limited activity against Gram-positive bacteria. Carbenicillin binds and inhibits the enzymes involved in the synthesis of bacterial cell wall. Since carbenicillin is less sensitive to β-lactamases than ampicillin, it is effective against ampicillin-resistant bacteria. It has superior stability at low pH and acts as a selection agent. Effective concentration of carbenicillin: 50 to 100 μg/ml.
Components: (per vial, sufficient for 500 ml medium)
Carbenicillin 25 mg
Storage Temp. 2-8°C
