Biological Activity

[Description]:

Nitrocefin is a chromogenic β-lactamase substrate that undergoes 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[1].
