Product Overview
| Description | Elastase, like trypsin and chymotrypsin, is a serine protease that also hydrolyses amides and esters. It is produced in the pancreas as an inactive zymogen, proelastase, and activated in the duodenum by trypsin. Elastase is distinctive in that it acts upon elastin.This enzyme degrades elastin, collagen, and proteoglycan and has been implicated in the development of pulmonary emphesema and rheumatoid arthritis. Source: Human Neutrophil Biological Activity: 20-22units/mg protein. Unit Definition: The amount of enzyme that hydrolyzes one micromole of Meo-Suc-Ala-Pro-Val-pNA/minute at 25°C in 100mM Tris-HCl, pH 7.5, 500mM sodium chloride. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
