Nitrocefin
Based on 2 publication(s) in Google Scholar
Nitrocefin is a highly activated, chromogenic cephalosporin derivative. Nitrocefin is a chromogenic β-lactamase substrate. Nitrocefin undergoes a distinctive color change from yellow to red as the amide bond in the β-lactam ring is hydrolyzed by β-lactamase. Nitrocefin is used in competitive inhibition studies in developmental work on β-lactamase-resistant antibiotics.

Deficiency in peptidoglycan recycling promotes β-lactam sensitivity in Caulobacter crescentus. [Abstract]2025 Apr 9;16(4):e0297524. PMID: 40066998
Nitrocefin purchased from MedChemExpress. Usage Cited in: mBio. 2025 Apr 9;16(4):e0297524. [Abstract]
Cell lysates of WT, RP47 (∆sdpA), and RP56 (∆ampG) with and without ampicillin treatment were incubated with Nitrocefin solution (1 mg/mL) for 30 min. M2 buffer was used as a negative control. The appearance of red color product indicates a positive β-lactamase activity, while a consistent yellow color indicates the absence of activity.
