Anti-ZWILCH antibodies are used in the immunodetection of the protein zwilch kinetochore protein. In humans, the canonical protein has a reported length of 591 amino acid residues and a mass of 67.2 kDa. Its subcellular localization is in the chromosomes. Up to 2 different isoforms have been reported for this protein. A member of the ZWILCH protein family, ZWILCH is an important component of the mitotic checkpoint, which prevents cells from prematurely exiting mitosis. Synonyms for this target antigen include hZwilch, protein zwilch homolog, Zwilch, kinetochore associated, homolog, homolog of Drosophila Zwilch, and KNTC1AP. ZWILCH gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ZWILCH antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
