Assay by immunoelectrophoresis resulted in a single precipitin arc against purified and partially purified Elastase [Porcine Pancreas]. Cross reactivity against Elastase from other tissues and species may occur but have not been specifically determined.
纯化方法
Prepared from monospecific antiserum by a delipidation and defibrination.
Suitable for Immunoblotting (Western or Dot blot), ELISA, Immunoprecipitation and mostimmunological methods requiring high titer and specificity. Recommended Dilutions: : This product has been assayed against 1.0 μg of Elastase[Porcine Pancreas] in a standard sandwich ELISA using Peroxidase conjugated AffinityPurified anti-Rabbit IgG [H&L] (Goat) and ABTS(2,2'-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) as a substrate for 30 minutes atroom temperature. A working dilution of 1: 5,000 to 1: 20,000 of the reconstitutionconcentration is suggested for this product. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

CELA1
(Chymotrypsin-Like Elastase Family, Member 1 (CELA1))
Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin. Elastase is a serine protease which exhibits endopeptidase activity on many proteins, its principal substrate, however, is elastin and it is unique among proteases in its ability to hydrolyse native elastin. It is present in the pancreas, leukocytes and serum. Elastase consists of a single polypeptide chain with a molecular weight of 29.5 kDa. Humans have six elastase genes which encode the structurally similar proteins elastase 1, 2, 2A, 2B, 3A, and 3B. Like most of the human elastases, elastase 2A is secreted from the pancreas as a zymogen. In other species, elastase 2A has been shown to preferentially cleave proteins after leucine, methionine, and phenylalanine residues. Elastase 1 is not a pancreatic enzyme: clinical literature that describes human elastase 1 activity in the pancreas is actually referring to elastase 2A.Synonyms: CELA1, Chymotrypsin-like elastase family member 1, ELA1
