MilliporeSigma™ Calbiochem™ CENTA™ β-Lactamase Substrate

Description

• Chromogenic β-lactamase substrate for both gram-negative and gram-positive bacteria that is comparable to other chromogens (PADAC™ Substrate and nitrocefin)
• Hydrolysis of the beta-lactam ring causes a color change from light yellow (λ max : 340 nm) to chrome yellow (λ max : 405 nm)
• Relatively unaffected by commonly used microbiological media and human serum
• Stable in H 2 O and in the presence of cysteine, mercaptoethanol and dimercaptopropanol
• Please note that the molecular weight for this compound is batch-specific due to variable water content.
