| Pepsin | Pepsin is a digestive enzyme: It is extracted from Pepsinogen under pH 1.5-5.0 and the pepsinogen is secreted by the stomach cell. Pepsin can decompose the solidified proteins into peptone by effect of stomach acid, but it can not go any further to amino acid. The best effective condition for pepsin is pH 1.6-1.8. Applications: It is widely used for the dyspepsia caused by over taking proteinic foods and lack of stomach proteinase caused by digestive hypofunction in the recovering period. it also has effect on curing chronic atrophic gastritis, gastric cancer and malignant anaemia. pepsin is extracted from porcine gastric mucosa through our exclusive skill.

| Immobilized Pepsin (Agarose Resin) | Immobilized Pepsin allows efficient generation of F(ab?)2 from IgG. Pepsin is a nonspecific endopeptidase that is active only at acid pH and irreversibly denatured at neutral or alkaline pH. Immobilized Pepsin is advantageous because the digestion can be immediately stopped by simply removing the gel from the IgG. Digestion by pepsin normally produces a F(ab?)2 fragment and numerous small peptides of the Fc portion. The resulting F(ab?)2 fragment is composed of two disulfide-connected Fab units. The Fc fragment is extensively degraded, and its small fragments can be separated from F(ab?)2 by dialysis, gel filtration or ion exchange chromatography. Group: Enzymes. Synonyms: Immobilized Pepsin. Enzyme Commission Number: EC 3.4.23.1. Pepsin. Storage: Upon receipt store product at 4-8°C. Product is shipped at ambient temperature.

| Native Porcine Pepsinogen | Pepsinogen is the zymogen of pepsin. It is processed by autocatalytic cleavage of 44 amino acids to generate active pepsin. Serum levels of pepsinogen have been measured to identify gastric cancer risk. Applications: Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides. it was discovered in 1836 by theodor schwann who also coined its name from the greek word π?ψΙ? pepsis, meaning "digestion" (from π?πτεΙν peptein "to digest"). it was the first enzyme to be discovered, and, in 1928, it became one of the first enzymes to be crystallized, by john h. northrop. ...rticular types of amino acids, collaborate to break down dietary proteins into their components, i.e., peptides and amino acids, which can be readily absorbed by the intestinal lining. pepsin is most efficient in cleaving peptide bonds between hydrophobic and preferably aromatic amino acids such as phenylalanine, tryptophan, and tyrosine.
