설명

일반 설명

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

제조 메모

Preparing a Nitrocefin (500 µg/ml) Solution

• Dissolve 1 mg Nitrocefin in 100 µl dimethylsulfoxide (DMSO) and vortex.

• Add 1.9 ml phosphate buffer (100 mM, pH 7) to produce 2 ml total volume.

• This yields a working Nitrocefin solution of 500 µg/ml (~1 mM), which is suitable for most applications.

• Nitrocefin, particularly in solution, is very sensitive to light.

재구성

Following reconstitution, aliquot and freeze (-20°C). Stock solution may be stored at -20°C for up to 2 weeks.
