Product Overview

Cefoxitin Sodium Salt is a second-generation β-lactam cephamycin antibiotic widely used in microbiological research, antimicrobial susceptibility testing, and resistance mechanism studies.

Cefoxitin exhibits activity against a range of Gram-positive and Gram-negative bacteria and is structurally resistant to many β-lactamase enzymes, making it particularly useful in laboratory evaluation of resistance patterns.

Ausamics Cefoxitin Sodium Salt Powder is supplied as a high-purity research-grade material, manufactured under controlled quality systems to ensure analytical consistency and reproducible laboratory performance.

Mechanism of Action

Cefoxitin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), preventing peptidoglycan cross-linking and resulting in bactericidal activity in susceptible organisms.
