Anti-HPA3 antibodies enable researchers to detect and measure the HPA3 antigen in biological samples. This target is a reported synonym of the ITGA2B gene, which encodes integrin subunit alpha 2b. This protein is known to function in angiogenesis and cell adhesion, among other biological roles. The human version of HPA3 has a canonical amino acid length of 1039 residues and a protein mass of 113.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the membrane of cells and notably expressed in the bone marrow and placenta. Other names for this target antigen include BDPLT16, BDPLT2, and CD41. Flow Cytometry and Western Blot are common applications for HPA3 antibodies.
