Description

Chromogenic beta-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 (lambdamax: 340 nm) to chrome yellow (lambdamax: 405 nm). Relatively unaffected by commonly used microbiological media and human serum. Stable in H2O 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., Chromogenic beta-lactamase substrate for both gram-negative and gram-positive bacteria that is comparable to other chromogens (PADAC and nitrocefin).
