Anti-SP5 antibodies are used in the immunodetection of the protein Sp5 transcription factor. In humans, the canonical protein has a reported length of 398 amino acid residues and a mass of 42 kDa. Its subcellular localization is in the nucleus. A member of the Sp1 C2H2-type zinc-finger protein family, SP5 is known to bind to GC boxes promoters elements. Synonyms for this target antigen include transcription factor Sp5. SP5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SP5 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
