Anti-A-259H10.2 antibodies enable researchers to detect and measure the A-259H10.2 antigen in biological samples. This target is a reported synonym of the HPR gene, which encodes haptoglobin-related protein. The human version of A-259H10.2 has a canonical amino acid length of 348 residues and a protein mass of 39 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in the liver. This target antigen may also be known as A-259H10.2.
