Neutrophil Elastase Inhibitor Assay Kit

Product details

How the assay works

In Neutrophil Elastase Inhibitor Assay Kit protocol, Neutrophil Elastase hydrolyzes a specific fluorescent substrate to release the fluorescent group, which can be detected at Ex/Em = 400/505 nm. In presence of a potent neutrophil elastase inhibitor, the hydrolyzation of substrate will be inhibited or stopped. For comparison of the relative efficacy of test inhibitors, a control inhibitor, SPCK (Ki = 10 µM for human leukocyte elastase) is included.
