Anti-SRARP antibodies are used in the immunodetection of the protein steroid receptor associated and regulated protein. In humans, the canonical protein has a reported length of 169 amino acid residues and a mass of 17.7 kDa. It is reported to be expressed in breast tumors with a higher expression level in estrogen receptor-positive cancers. SRARP is believed to regulate the transcriptional function of androgen and estrogen receptors. Synonyms for this target antigen include estrogen receptor-related factor, steroid receptor-regulated protein, uncharacterized protein C1orf64, and ER-related factor. SRARP gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some SRARP antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
