Anti-CD42b antibodies enable researchers to detect and measure the CD42b antigen in biological samples. This target is a reported synonym of the GP1BA gene, which encodes glycoprotein Ib platelet subunit alpha. This protein is known to function in cell adhesion and receptor-mediated signaling pathways, among other biological roles. The human version of CD42b has a canonical amino acid length of 652 residues and a protein mass of 71.5 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the bone marrow and spleen. Other names for this target antigen include BDPLT1, BDPLT3, and BSS.
