Anti-HDR antibodies enable researchers to detect and measure the HDR antigen in biological samples. This target is a reported synonym of the GATA3 gene, which encodes GATA binding protein 3. This protein is known to function in the morphogenesis of anatomical structure and axon guidance, among other biological roles. The human version of HDR has a canonical amino acid length of 443 residues and a protein mass of 47.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the breast and kidney. Some HDR antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
