Product Summary for Mouse Neutrophil Elastase/ELA2 Quantikine ELISA Kit

The Quantikine® Mouse Neutrophil Elastase/ELA2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure ELA2 in cell culture supernates, tissue lysates, serum, and plasma. It contains NS0-expressed recombinant mouse ELA2 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse ELA2. Results obtained using natural mouse ELA2 showed linear curves that were parallel to the standard curves obtained using the Quantikine® kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse ELA2.

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of mouse ELA2 were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.

Background: Neutrophil Elastase/ELA2

Neutrophil Elastase (ELA2), also known as polymorphonuclear leukocyte elastase, is a serine protease belonging to the chymotrypsin family. Located primarily in the azurophil granules of polymorphonuclear leukocytes, ELA2 function results in the degradation of many extracellular matrix macromolecules. Alpha-1 Antitrypsin (Serpin A1) and secretory leukocyte protease inhibitor (SLPI) have been shown to inhibit ELA2 activity. ELA2 may be involved in lung emphysema, cystic fibrosis, the adult respiratory distress syndrome (ARDS), rheumatoid arthritis, tumor invasion and infectious diseases.
