cystatin SN Antibody (SN21): sc-73885

Cystatin SN Antibody (SN21) is a mouse monoclonal IgG2b antibody that detects cystatin SN in human samples through applications such as western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). Cystatin SN is a member of the cystatin superfamily, which plays a crucial role in regulating proteolytic activity by inhibiting cysteine proteases, particularly those from the papain family, including cathepsins. Anti-cystatin SN antibody (SN21) helps researchers understand this regulation, which is vital for maintaining cellular homeostasis and protecting tissues from excessive proteolysis that can lead to various pathological conditions. Cystatin SN is predominantly found in saliva, but also expressed in tears, urine, and seminal fluid, highlighting its importance in mucosal immunity and tissue protection. The presence of cystatin SN in these bodily fluids suggests a potential role in safeguarding epithelial surfaces from proteolytic damage, contributing to the overall defense mechanisms of the human body. Cystatin SN monoclonal antibody (SN21) serves as an essential tool for investigating the functions and interactions of cystatin SN in health and disease, providing insights into its protective roles and potential therapeutic applications.

The preferred cystatin S/SA/SN antibody is cystatin S/SA/SN Antibody (Z8983): sc-73884.
