Beta Lactamase Activity Assay Kit (Colorimetric)

Beta Lactamase Activity Assay Kit (Colorimetric) ab197008 is a simple and sensitive assay that can detect and quantify the enzymatic activity of beta lactamases, a large family of hydrolases.

The beta lactamase assay protocol is based on the hydrolysis of the substrate Nitrocefin, a chromogenic cephalosporin, that results in the generation of a colored product (detectable at OD=490 nm), which is directly proportional to the amount of beta-lactamase activity.

This product can detect as low as 0.06 mU of beta-lactamase activity from bacterial samples or from biological fluids infected with beta-lactamase expressing bacteria.

Beta lacatmase assay protocol summary:
- add samples and standards to wells
- add reaction mix
- analyze with a microplate reader in kinetic mode every 2-3 min for 30-60 min

This product is manufactured by BioVision, an Abcam company and was previously called K803 Beta-Lactamase Activity Colorimetric Assay Kit. K803-100 is the same size as the 100 test size of ab197008.

Beta Lactamases (β-Lactamases, βLs), are a large family of hydrolases comprising more than 850 identified members expressed in Gram-positive and Gram-negative bacteria. βLs can be classified according to their substrate or inhibitor specificity. These enzymes are capable of hydrolyzing four atom rings known as β-lactams.
