Description

Pepsin is the major pig and human gastric proteases, it is a pepsin-like minor gastric proteolytic enzymes. Pepsin contributes to proteolysis of food proteins in the vertebrate stomach[1][2].

In Vitro

Optimal pH: 1.0-3.0.
Activators: Hydrochloric acid (HCl), trifluoroacetic acid (TFA).
Inactivators: pH greater than 6.0.
Usage Notes:
1. Resuspend Pepsin in double-distilled water (pH 5.5 or lower) to a final concentration of 1mg/mL. Store reconstituted Pepsin at 4 °C for up to 1 month.
2. Specificity for cleavage at Phe and Leu is best at pH 1.0 and decreased above pH 2.0. Pepsin irreversibly inactivates above pH 6.0.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
