Anti-HNF4 antibodies enable researchers to detect and measure the HNF4 antigen in biological samples. This target is a reported synonym of the HNF4A gene, which encodes hepatocyte nuclear factor 4 alpha. This protein is known to function in cell differentiation and cholesterol metabolism and homeostasis, among other biological roles. The human version of HNF4 has a canonical amino acid length of 474 residues and a protein mass of 52.8 kilodaltons, although 7 isoforms have been identified. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the appendix and colon. Other names for this target antigen include FRTS4 and HNF4a7. Western Blot is the most common application for the HNF4 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
