Product Information
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.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
