Anti-HMG20A antibodies are used in the immunodetection of the protein high mobility group 20A. In humans, the canonical protein has a reported length of 347 amino acid residues and a mass of 40.1 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. HMG20A is reported to play a role in neuronal differentiation as chromatin-associated protein. Synonyms for this target antigen include HMGXB1, high mobility group protein 20A, HMG box domain containing 1, HMG box-containing protein 20A, HMG domain-containing protein 1, and HMGX1. HMG20A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of HMG20A antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
