Anti-GPIbalpha antibodies are protein reagents that detect specific antigens. The GPIbalpha antigen is another term for the human protein glycoprotein Ib platelet subunit alpha, encoded by the GP1BA gene. The protein is known to function in cell adhesion and receptor-mediated signaling pathways, among other biological roles. Canonically, it has an amino acid length of 652 residues and a mass of 71.5 kilodaltons. Its subcellular localization is in the membrane and it is expressed in the bone marrow and spleen. Other alias names for GPIbalpha include BDPLT1, BDPLT3, and BSS. Flow Cytometry is a widely used application for the GPIbalpha antibodies listed below. In addition, ELISA is also a common application.
