Description

Streptomyces Pepsin Inhibitor CAS NO 11076-29-2 is a specific, low-molecular-weight proteinase inhibitor derived from *Streptomyces* species. This compound is essential for controlling and studying pepsin activity in biochemical and pharmaceutical research. It is a critical reagent for researchers and manufacturers in the life sciences, pharmaceutical development, and diagnostic industries who require precise enzyme inhibition for assay development, protein purification, and therapeutic research.

Application

• Biochemical Research & Assay Development: Used as a specific inhibitor to study pepsin's role in protein digestion, enzyme kinetics, and proteolytic pathways in vitro.
• Pharmaceutical R&D: Employed in drug discovery programs targeting gastrointestinal disorders or conditions involving excessive pepsin activity.
• Diagnostic Kit Manufacturing: Incorporated as a key component in diagnostic assays and kits designed to measure pepsin levels or activity in clinical samples.
• Protein Purification & Proteomics: Utilized to prevent unwanted proteolytic degradation by pepsin during the isolation and purification of sensitive proteins and peptides.
• Cell Culture & Biotechnology: Applied in cell culture media and bioprocessing to inhibit pepsin-like activity that could compromise product yield or stability.
• Academic & Teaching Laboratories: Serves as a standard tool for demonstrating principles of enzyme inhibition and protease specificity in educational settings.
