Application

Beta-Lactamase Inhibitor Screening Kit has been used in enzymatic assays.

Features and Benefits

Compatible with high-throughput handling systems.

General description

β-Lactamase (β-lactamase, βL, EC 3.5.2.6) is an enzyme first identified in Escherichia coli and has been described as penicillinase. A number of βLs have since been identified from various bacteria. β-Lactamases specifically hydrolyze β-lactam rings present in antibiotics such as penicillin, cephalosporins, monobactam, and carbapenem, and confer resistance against these antibiotics.

Principle

The β-Lactamase Inhibitor Screening Kit is a rapid, simple and sensitive assay that is suitable for high throughput screening of β-Lactamase inhibitors. βL activity is measured by hydrolyzing a chromogenic cephalosporin called nitrocefin, producing a colorimetric product (A490), proportional to the enzymatic activity present.

Suitability

Suitable for the screening of inhibitors of β-Lactamase
