Nitrocefin – CAS 41906-86-9 – Calbiochem

Descrição detalhada : A chromogenic beta-lactamase substrate that undergoes distinctive color change from yellow (lambdamax = 390 nm at pH 7.0) to red (lambdamax = 486 nm at pH 7.0) as the amide bond in the beta-lactam ring is hydrolyzed by beta-lactamase. Nitrocefin is sensitive to hydrolysis by all known lactamases produced by Gram-positive and Gram-negative bacteria. Also useful for the detection of beta-lactamase patterns from bacterial cell extracts by isoelectric focusing. Has been used in competitive inhibition studies in developmental work on beta-lactamase-resistant antibiotics.
