Anti-SPIDR antibodies are used in the immunodetection of the protein scaffold protein involved in DNA repair. In humans, the canonical protein has a reported length of 915 amino acid residues and a mass of 100.3 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. SPIDR is reported to play a role in DNA double-strand break (DBS) repair via homologous recombination (HR). The SPIDR gene has been associated with the disease, Ovarian dysgenesis. Synonyms for this target antigen include ODG9, DNA repair-scaffolding protein, scaffolding protein involved in DNA repair, and KIAA0146. SPIDR gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunocytochemistry is the most common application for the SPIDR antibodies listed below. Western Blot and Immunofluorescence are also common applications.
