Anti-DNAH9 antibodies are used in the immunodetection of the protein dynein axonemal heavy chain 9. In humans, the canonical protein has a reported length of 4486 amino acid residues and a mass of 511.9 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in upper and lower respiratory airway epithelia. A member of the Dynein heavy chain protein family, DNAH9 is known to be involved with cellular localization. The DNAH9 gene has been associated with the disease, Ciliary dyskinesia. Synonyms for this target antigen include DNAH17L, DNEL1, DYH9, Dnahc9, HL-20, HL20, DNAH9 variant protein, and CILD40. DNAH9 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of DNAH9 antibodies have been mentioned in research publications and have associated citations. Immunofluorescence is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
