Product Overview

Cefotaxime Sodium Salt is a third-generation β-lactam cephalosporin antibiotic widely used in microbiological and molecular biology research.

It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), preventing peptidoglycan cross-linking and resulting in bactericidal activity under laboratory conditions.

Due to its broad activity against Gram-negative and certain Gram-positive organisms, cefotaxime is commonly used as:

• A selective agent in microbial culture systems

• A bacterial elimination agent in plant tissue culture

• A tool for resistance mechanism studies

Ausamics Cefotaxime Sodium Salt is manufactured under controlled quality systems and analytically verified for purity and performance consistency.

Key Applications

• Plant tissue culture (Agrobacterium elimination)

• Microbiological selective media

• Antimicrobial susceptibility research

• β-lactam resistance mechanism studies

• Molecular biology workflows

Mechanism of Action

Cefotaxime inhibits bacterial cell wall synthesis by binding to PBPs involved in peptidoglycan assembly.
This disrupts cell wall integrity, leading to bacterial lysis in susceptible strains.
