Description

Pepsin CAS NO 9001-76-7 is a proteolytic enzyme derived from the gastric mucosa of animals, primarily pigs, and is essential for the digestion of proteins. This high-activity enzyme is critical for ensuring efficient and specific protein hydrolysis in various industrial and research processes. It is a vital raw material for pharmaceutical manufacturers, diagnostic kit producers, and food processing industries seeking reliable enzymatic activity for product development and quality control.

Application

• Pharmaceutical Manufacturing: Used as a digestive aid in enzyme replacement therapies and as an active pharmaceutical ingredient (API) in certain medicinal products.
• Diagnostic Reagents: Employed in clinical and research laboratories for tissue dissociation, cell isolation, and as a component in various biochemical assay kits.
• Food & Beverage Processing: Applied in the production of protein hydrolysates, flavor enhancers, and in the clarification of beverages.
• Biotechnology & Research: Utilized for protein digestion in peptide mapping, mass spectrometry sample preparation, and other proteomics research applications.
• Leather Processing: Acts in the bating stage to remove unwanted proteins and soften hides.
• Dietary Supplements: Formulated into digestive enzyme supplements to support protein digestion.
