          Description
          OverviewA chromogenic β-lactamase substrate that undergoes distinctive color change from yellow (λmax = 390 nm at pH 7.0) to red (λmax = 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.

          Recommended reaction conditions
          Techniques for the Rapid Detection of β-Lactamase Using Nitrocefin 1. Direct Plate Method Add one drop of the Nitrocefin working solution on to the surface of the colony. If the isolate is a high β-lactamase producer then the colony and the surrounding area will turn red quickly. 2. Slide Method Add one drop of the Nitrocefin working solution on to the surface of a clean glass slide. Using a sterile loop, pick one colony from the plate and emulsify into the Nitrocefin drop. Report as positive for β-lactamase if the color changes from yellow to red within 30 min. NOTE: Protect the slide from desiccation during the waiting period. 3. Broth Method Add four drops of the Nitrocefin solution to 1 ml of the grown culture. Report as positive for β-lactamase if the color changes to red within 30 min. 4. Broken Cell Method Sonicate 1 ml of the culture in order to break open the cells. Add 4 drops of the Nitrocefin working solution. Report as positive for β-lactamase if the color changes to red within 30 min. 5. Paper Disc Spot Method Place a Whatman No. 1 filter paper disc (diameter 7 cm) in a petri dish and impregnate with 5 ml of the Nitrocefin working solution. Apply an isolated colony to the impregnated paper disc using a sterile loop. A pink to red reaction developing within 15 min indicates the presence of β-lactamase. NOTE: The impregnated paper disc is stable for one day, if protected from light to avoid degradation. 6. Spectrophotometric Assays for Determining β-Lactamase Activity The working solution of Nitrocefin (500 µg/ml) is diluted ten-fold in buffer (0.1 M phosphate; 1 mM EDTA, pH 7.0). Spectrophotometric assays for β-Lactamase using Nitrocefin are carried out by measuring changes in absorbance at 486 nm. The molar extinction coefficient of hydrolyzed Nitrocefin at 486 nm is 20,500 M-1 cm-1. Test samples of the finished product for performance with control cultures.

          SolubilityPreparing 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.
