Description

Cystatin Alpha CAS NO 107935-53-5 is a low molecular weight protein belonging to the cystatin superfamily of cysteine protease inhibitors. This compound is of significant interest in biochemical and pharmaceutical research due to its role in regulating proteolytic activity. It is primarily utilized by research institutions and biotechnology companies focused on protease-related pathways, inflammation studies, and the development of diagnostic markers.

Application

• Biochemical Research: Used as a specific inhibitor in studies of cysteine proteases like cathepsins to elucidate enzyme kinetics and regulatory mechanisms.
• Diagnostic Development: Serves as a reference standard or antigen in the development of immunoassays for research into inflammatory and renal conditions.
• Pharmaceutical R&D: Investigated for its therapeutic potential in diseases involving unbalanced proteolysis, such as certain cancers, osteoporosis, and neurodegenerative disorders.
• Cell Culture & Protein Studies: Employed in in vitro systems to control unwanted proteolytic degradation and stabilize proteins of interest.
