Background Information
ELA2(Neutrophil elastase) is also named as ELAL, NE, HLE, HNE, PMN-E, SERP1, GE, ELANE and belongs to the peptidase S1 family. It is a 33-kDa enzyme with several isoforms that differ in their extent of glycosylation(PMID:12223222). Human neutrophil elastase (HNE) is a serine protease with potent proteolytic activity (3), which is reported to cause mucin secretion (degranulation)(PMID:12169572). It may contribute to the directed migration of leukocytes into flamed postcapillary venules in addition to contributing to the process of tissue emigration(PMID:9683424). The full length protein has a signal peptide,propeptide and three glycosylation sites.

Clotilde (Verified Customer) (07-13-2026) | This Elastase works perfectly in IF-P. The IF was performed on FFPE human tonsil tissue slide with Dako antigen retrival pH9. Primary incubation was performed at 1:100 overnight (16h) at 4°C. Secondary incubation was performed with Goat anti-Rabbit at 1:1000 for 1h at RT. Image were taken with a Leica THUNDER at 10x and 20x magnification.
