Anti-SATB1 antibodies are used in the immunodetection of the protein SATB homeobox 1. In humans, the canonical protein has a reported length of 763 amino acid residues and a mass of 86 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in thymus. A member of the CUT homeobox protein family, SATB1 is known to be involved with chromatin organization and chromatin remodeling. Synonyms for this target antigen include KTZSL, DNA-binding protein SATB1, special AT-rich sequence binding protein 1 (binds to nuclear matrix/scaffold-associating DNA), and DEFDA. SATB1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 60 citations in the literature describe the use of SATB1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
