{"product_id":"new-product-273909","title":"Pepsin A (M307) polyclonal antibody","description":"\u003cp\u003ePepsin consists of a single polypeptide chain and arises from its precursor, pepsinogen, by removal of a 41 amino acid segment from the N-terminus. Pepsinogen is synthesized in the stomach lining, and hydrochloric acid, also produced by the gastric mucosa, is necessary to convert the inactive enzyme and to maintain the optimum acidity (pH 1-3) for pepsin function. Pepsin is particularly effective in cleaving peptide bonds involving aromatic amino acids. Pepsin shows extremely broad specificity; although bonds involving phenylalanine and leucine are preferred, many others are also cleaved to some extent. Pepsin A is a member of the subfamily A1 within the pepsin family and is the predominant endopeptidase in the gastric juice of vertebrates. Pepsin A is inhibited by ovUS-1, a uterine serpin.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":45803644649752,"sku":"ABCBW01999","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_d1d5df80-1892-4776-aba9-0c8da064c59e.png?v=1689736399","url":"https:\/\/danabiosci.com\/products\/new-product-273909","provider":"Dana Bioscience","version":"1.0","type":"link"}
