Anti-ADB2 antibodies enable researchers to detect and measure the ADB2 antigen in biological samples. This target is a reported synonym of the ITGAD gene, which encodes integrin subunit alpha D. This protein is known to function in cell adhesion and cell matrix adhesion, among other biological roles. The human version of ADB2 has a canonical amino acid length of 1161 residues and a protein mass of 126.8 kilodaltons. It is reported to be localized in the membrane of cells. Other names for this target antigen include CD11D and integrin alpha-D.
