Description

Streptomyces Trypsin Inhibitor 1 CAS NO 119632-51-8 is a highly specific, low molecular weight proteinase inhibitor derived from *Streptomyces* bacteria. This compound is critical for controlling proteolytic activity in sensitive biochemical and biopharmaceutical processes. It is an essential research and production reagent for scientists and manufacturers in the life sciences, biotechnology, and pharmaceutical development sectors.

Application

• Biochemical Research: Used as a specific inhibitor in enzymatic studies to investigate trypsin and trypsin-like protease functions in metabolic pathways and signal transduction.
• Biopharmaceutical Production: Employed in downstream processing to prevent unwanted proteolytic degradation of therapeutic proteins, peptides, and antibodies during purification.
• Cell Culture & Tissue Engineering: Added to serum-free or defined media formulations to protect cells from protease activity, enhancing cell viability and product yield.
• Diagnostic Reagent Formulation: Serves as a stabilizing agent in diagnostic kits and assays to ensure the specificity and longevity of protease-dependent reactions.
• Structural Biology Studies: Utilized in crystallography and NMR studies to form stable complexes with trypsin, aiding in the determination of enzyme-inhibitor structures.
• Proteomics Sample Preparation: Prevents sample degradation during the extraction and preparation of proteins for mass spectrometry analysis.
