Description:

WARNING: This product is for research use only, not for human or veterinary use.

Cefmetazole is a second-generation, semi-synthetic, beta-lactam cephalosporin antibiotic with antibacterial activity. Cefmetazole binds to penicillin-binding proteins (PBPs) that are responsible for crosslinking of peptidoglycan. By preventing crosslinking of peptidoglycan, cell wall integrity is lost and cell wall synthesis is halted.
