Pepsin is most active in acidic environments between pH 1.5 to 2.5. Accordingly, its primary site of synthesis and activity is in the stomach (pH 1.5 to 2). In humans the concentration of pepsin in the stomach reaches 0.5 – 1 mg/mL. Pepsin is inactive at pH 6.5 and above, however pepsin is not fully denatured or irreversibly inactivated until pH 8.0. Therefore, pepsin in solutions of up to pH 8.0 can be reactivated upon r… WebCleaning solution Pepsin-HCl, 250mL - Overview - METTLER TOLEDO. Products & Solutions. Industries. Services & Support.
