Description

Trypsin Inhibitor CAS NO 91755-87-2 is a high-purity, biologically active protein that specifically inhibits the proteolytic enzyme trypsin. This precise inhibition is critical for controlling unwanted proteolysis in a wide range of biochemical and biopharmaceutical processes. It is an essential reagent for researchers and manufacturers in life sciences, diagnostic development, and bioprocessing who require reliable and consistent enzyme control to ensure experimental integrity and product stability.

Application

• Cell Culture & Bioprocessing: Used to inhibit trypsin activity after cell detachment, protecting cells from proteolytic damage and improving cell viability and recovery.
• Protein Biochemistry Research: Essential for studying protease function, enzyme kinetics, and protein-protein interactions where specific trypsin inhibition is required.
• Diagnostic Kit Manufacturing: Incorporated into immunoassay and clinical diagnostic kits to stabilize protein components and prevent sample degradation by endogenous proteases.
• Pharmaceutical Development: Employed in downstream purification processes to protect therapeutic proteins, peptides, and antibodies from proteolytic cleavage.
• Food Science & Analysis: Applied in food protein analysis and functional studies to investigate the role of trypsin and other serine proteases.
