Description

Trypsin Inhibitor CAS NO 9078-38-0 is a high-purity protein-based reagent that specifically inhibits the proteolytic activity of trypsin. This compound is critical for controlling enzymatic digestion in research and industrial processes, ensuring experimental accuracy and product stability. It is an essential component for biotechnology, pharmaceutical development, and diagnostic manufacturing, where precise enzyme regulation is required.

Application

• Cell Culture & Proteomics Research: Used to prevent unwanted trypsinization and protein degradation during cell harvesting and protein sample preparation.
• Pharmaceutical Formulation: Acts as a stabilizing agent in biopharmaceutical products to protect active protein ingredients from proteolytic breakdown.
• Diagnostic Kit Manufacturing: Incorporated into enzyme-linked immunosorbent assay (ELISA) and other diagnostic reagents to control background enzymatic activity.
• Biochemical Research: Serves as a standard and control in enzymatic studies to investigate protease function and inhibition mechanisms.
• Food Science & Analysis: Employed in analytical methods to measure trypsin-like activity in food products or to study protein digestibility.
