General description

(from porcine gastric mucosa) cryst. lyophilized 10 FIP-U/mg for biochemistry EC 3.4.23.1
Protease
Pepsin is a member of the small family of closely related aspartic proteinase enzymes. Pepsin hydrolyzes proteins and petides, including those with bonds adjacent to aromatic or dicarboxylic L-amino acid residues; preferential cleavage: Phe- and Leu-.

Application

Pepsin (from porcine gastric mucosa) cryst. lyophilized 10 FIP-U/mg for biochemistry EC 3.4.23.1. CAS 9001-75-6, pH 4.0 - 5.0 (10 g/l, H₂O, 20 °C), molar mass 35000 g/mol.
