Description

Streptomyces Trypsin Inhibitor 2 CAS NO 146810-96-0 is a highly specific, low molecular weight proteinase inhibitor derived from *Streptomyces* species. This compound is critical for controlling proteolytic activity in sensitive biochemical and biopharmaceutical processes, ensuring the integrity of target proteins. It is an essential reagent for researchers and manufacturers in life sciences, particularly for applications requiring precise enzyme regulation and high-purity biological preparations.

Application

• Biopharmaceutical Manufacturing: Used in downstream purification processes to inhibit trypsin and related serine proteases, protecting therapeutic proteins like monoclonal antibodies and growth factors from degradation.
• Cell Culture & Tissue Engineering: Added to serum-free media formulations to control protease activity, thereby enhancing cell viability, growth, and the yield of cell-derived products.
• Diagnostic Kit Production: Serves as a stabilizing agent in enzyme-based diagnostic assays and test kits to prevent false results caused by nonspecific proteolysis.
• Biochemical Research: A key tool for studying protease kinetics, enzyme inhibition mechanisms, and signal transduction pathways in academic and industrial R&D laboratories.
• Protein Crystallography: Employed to inhibit proteases during the purification and crystallization of proteins to obtain high-quality crystals for structural analysis.
• Food & Beverage Enzyme Processing: Applied to modulate enzymatic activity in specific food processing steps where controlled protein digestion is required.
