      Description
      OverviewChromogenic 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 (λmax: 340 nm) to chrome yellow (λmax: 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.
