General description

Native pepsin from porcine stomach mucosa. Active under acidic conditions. Catalyzes the hydrolysis of aminoacyl-proline to an amino acid and proline. Inhibitors include aliphatic alcohols, pepstatin A, and pH >6.0. Has an optimal pH of 2.0-4.0.
Native pepsin from porcine stomach mucosa. Secreted by the mucosal lining of the stomach. Active under acidic conditions. Catalyzes the hydrolysis of aminoacyl-proline to an amino acid and proline. Inhibitors include aliphatic alcohols, pepstatin A, and pH >6.0.

Warning

Toxicity: Harmful (C)

Unit Definition

One unit is defined as the amount of enzyme that will digest hemoglobin substrates to TCA-soluble products, measured as a change in absorbance at 280 nm of 0.001 per min at 37°C, pH 2.0.

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C.
