Anti-GpIIb antibodies are protein reagents that detect specific antigens. The GpIIb antigen is another term for the human protein integrin subunit alpha 2b, encoded by the ITGA2B gene. The protein is known to function in angiogenesis and cell adhesion, among other biological roles. Canonically, it has an amino acid length of 1039 residues and a mass of 113.4 kilodaltons. Its subcellular localization is in the membrane and it is expressed in the bone marrow and placenta. The GpIIb protein is a member of the Integrin alpha chain protein family. Other alias names for GpIIb include BDPLT16, BDPLT2, and CD41. These GpIIb antibodies are widely used in Flow Cytometry experiments, among other applications.
