Anti-SPAG17 antibodies are used in the immunodetection of the protein sperm associated antigen 17. In humans, the canonical protein has a reported length of 2223 amino acid residues and a mass of 251.7 kDa. Its subcellular localization is in the cytoplasmic vesicles, Golgi, and cytoplasm. It is reported to be highly expressed in the testis. SPAG17 is a known component of the central pair apparatus of ciliary axonemes. The SPAG17 gene has been associated with the disease, Spermatogenic failure. Synonyms for this target antigen include projection protein PF6 homolog. SPAG17 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunofluorescence is a widely used application for the SPAG17 antibodies listed below. In addition, Immunocytochemistry is also a common application.
