Description

A broad spectrum antibiotic | CAS: 104010-37-9 | C19H16N5NaO7S3 | 545.53 g/mol

Ceftiofur sodium is resistant to the antibiotic resistance enzyme beta-lactamase, and has activity against Gram-positive and Gram-negative bacteria. E. coli strains resistant to ceftiofur have been reported. The bactericidal activity of ceftiofur results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins. The PBPs are transpeptidases which are vital in peptidoglycan biosynthesis. Therefore, their inhibition prevents this vital cell wall component from being properly synthesized.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
