Neutrophil Elastase Activity Assay Kit (Fluorometric) ab204730 is based on the ability of neutrophil elastase (NE) to
proteolytically cleave a synthetic substrate in order to release a fluorophore, AFC (Ex/Em 380/500 nm), which can be
easily quantified by fluorescence microplate readers.
This assay kit is simple, rapid and can detect as low as 1 ng of Neutrophil Elastase in a variety of samples.
Neutrophil elastase assay protocol summary:
- add samples and standards to wells
- add reaction mix
- analyze with a microplate reader every 2-3 min for 10-20 min
This product is manufactured by BioVision, an Abcam company and was previously called K383 Neutrophil Elastase
Activity Assay kit (Fluorometric). K383-100 is the same size as the 100 test size of ab204730.
Neutrophil Elastase (NE, EC 3.4.21.37, leukocyte elastase, ELANE, ELA2, elastase 2, neutrophil elaszym, or serine
elastase) is a cytotoxic serine protease. It is stored in the azurophil granules of neutrophil granulocyte and is released
following cell stimulation, e.g. by pathogens, immune complexes or chemotactic agents (PMA). When the
extracellular NE concentration exceeds the buffering capacity of endogenous inhibitors, it causes degradation of a
wide range of extracellular matrix proteins, including fibronectin, laminin, proteoglycans, collagens, and elastin.
