Anti-KIF21B antibodies are used in the immunodetection of the protein kinesin family member 21B. In humans, the canonical protein has a reported length of 1637 amino acid residues and a mass of 182.7 kDa. Its subcellular localization is in the cytoplasmic vesicles and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the Kinesin protein family. Synonyms for this target antigen include kinesin-like protein KIF21B. KIF21B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of KIF21B antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
