Anti-PEPSIN

Anti-PEPSIN is an IgG fraction antibody purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above.  Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Goat Serum as well as purified and partially purified Pepsin [Porcine Stomach].  Cross reactivity against Pepsin from other tissues and species may occur but have not been specifically determined. Protein function: Shows particularly broad specificity, although bonds involving phenylalanine and leucine are preferred, many others are also cleaved to some extent. [The UniProt Consortium]
