Description

Biochem/physiol Actions

Mode of Action: Penicillin G acts by inhibiting cell wall synthesis through binding to penicillin binding proteins (PBPs), inhibiting peptidoglycan chain cross-linking.

Antimicrobial spectrum: This product is active against gram-positive and gram-negative bacteria.

Caution

Solutions should be filter sterilized and stored at 2-8°C for 1 week or at -20°C for more lengthy periods. Solutions are stable at 37°C for 3 days. The potassium salt is soluble in H2O at 100 mg/mL.

Packaging

Application

Penicillin G is a narrow spectrum antibiotic derived from Streptococcus pneumoniae. It is the drug of choice for groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridians group streptococci, and non-penicillinase producing staphylococcus. The potassium salt has been used to study murosomes of staphylococci† and the penicillin-induced lysis of Streptococcus mutans.

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Handle and store under inert gas. Keep in a dry place.
