Anti-B2GP1 antibodies enable researchers to detect and measure the B2GP1 antigen in biological samples. This target is a reported synonym of the APOH gene, which encodes apolipoprotein H. This protein is known to function in the regulation of angiogenesis, among other biological roles. The human version of B2GP1 has a canonical amino acid length of 345 residues and a protein mass of 38.3 kilodaltons. It is reported to be a secreted protein. Other names for this target antigen include B2G1 and B2G1. These B2GP1 antibodies are widely used in Western Blot experiments, among other applications.
