Anti-KIF9 antibodies are used in the immunodetection of the protein kinesin family member 9. In humans, the canonical protein has a reported length of 790 amino acid residues and a mass of 90 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Kinesin protein family, Kif9 is known to be important for normal male fertility and for progressive motility of spermatozoa. Synonyms for this target antigen include kinesin-like protein KIF9 and kinesin protein 9. KIF9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some Kif9 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
