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.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
