Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin. Humans have six genes which encode the structurally similar proteins: Elastase 1, 2, 2A, 2B, 3A, and 3B. Unlike other elastases, 3B has little elastolytic activity. Like most of the human elastases, 3B is secreted from the pancreas as a zymogen and, like other serine proteases such as trypsin, chymotrypsin and kallikrein; it has a digestive function in the intestine. Elastase 3B preferentially cleaves proteins after alanine residues. It may also function in the intestinal transport and metabolism of cholesterol. Elastases 3A\/B have been referred to as Protease E and as Elastase 1, and excretion of this protein in fecal material is frequently used as a measure of pancreatic function in clinical assays.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhere multiple assay formats are possible, align the antibody format, host\/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.\u003c\/p\u003e \u003ch2\u003eBiological background\u003c\/h2\u003e \u003cp\u003eIn this catalog, CELA3B is positioned within \u003cstrong\u003eMolecular \u0026amp; Cellular Biology\u003c\/strong\u003e research contexts.
