ELISA Kit PrincipleAviva Systems Biology CD33 ELISA Kit (Human) (OKEH03363) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for CD33 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips) and blocked. Standards or test samples are added to the wells and incubated.After washing, a biotinylated detector antibody specific for CD33 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away.An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes yellow after adding acidicstop solution. The density of yellow coloration read by absorbance at 450 nm is quantitatively proportional to the amount of sample CD33 captured in well.

Description of TargetPutative adhesion molecule of myelomonocytic-derived cells that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules. Induces apoptosis in acute myeloid leukemia (in vitro).
