The Bioaim Human Cadherin S ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of Cadherin S in Human serum, plasma and cell culture media. An antibody specific for Human Cadherin S was coated on a 96-well plate. Standards and samples are added to the wells and any Cadherin S present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human Cadherin S antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of Cadherin S present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Angiogenesis;
Cathepsin S(Cathepsin S) Background: Cathepsin S is a lysosomal enzyme that belongs to the papain family of cysteine proteases. While a role in antigen presentation has long been recognized, it is now understood that cathepsin S has a role in itch and pain, or nociception. The nociceptive activity results from cathepsin S functioning as a signaling molecule via activation of protease-activated receptors 2 and 4 members of the G-protein coupled receptor family. Cathepsin S is expressed by antigen presenting cells including macrophages, B-lymphocytes, dendritic cells and microglia. The activity of cathepsin S is tightly regulated by its endogenous inhibitor, cystatin C, which also has a role in antigen presentation. Cystatin A and B have a lower activity compared to cystatin C.
