Anti-ARID1A antibodies are used in the immunodetection of the protein AT-rich interaction domain 1A. In humans, the canonical protein has a reported length of 2285 amino acid residues and a mass of 242 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. ARID1A is known to be involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). The ARID1A gene has been associated with the disease, Coffin-Siris syndrome. Synonyms for this target antigen include BAF250, BAF250a, BM029, C1orf4, CSS2, ELD, MRD14, and B120. ARID1A gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 340 citations in the literature describe the use of ARID1A antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
