Biological Activity
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.
