Elastase is a serine protease that also hydrolyzes amides and esters. It is produced as an inactive zymogen in the pancreas and activated by trypsin in the duodenum.
Product Introduction
Elastase is a serine protease that also hydrolyzes amides and esters. It is produced as an inactive zymogen in the pancreas and activated by trypsin in the duodenum.
Application
Tissue dissociation;
Increase the solubility of membrane protein;
Protein sequence study
Precautions
Poor solubility at neutral pH and concentrations greater than 0.25%. Before dilution into the reaction mixture or medium, it is best to prepare a primary solution in KCl or alkaline buffer to compensate for changes in ionic strength or pH. The pH value is stable at 4.0-10.4.
