Anti-HP2ALPHA2 antibodies enable researchers to detect and measure the HP2ALPHA2 antigen in biological samples. This target is a reported synonym of the HP gene, which encodes haptoglobin. The human version of HP2ALPHA2 has a canonical amino acid length of 406 residues and a protein mass of 45.2 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in the liver. Other names for this target antigen include BP and HPA1S. Some HP2ALPHA2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
