Anti-DNAH2 antibodies are used in the immunodetection of the protein dynein axonemal heavy chain 2. In humans, the canonical protein has a reported length of 4427 amino acid residues and a mass of 507.7 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in trachea and testis, 2 tissues containing axonemal structures. It is a member of the Dynein heavy chain protein family. The DNAH2 gene has been associated with the disease, Spermatogenic failure. Synonyms for this target antigen include ciliary dynein heavy chain 2, dynein heavy chain 2, axonemal, dynein heavy chain domain-containing protein 3, dynein, axonemal, heavy polypeptide 2, and axonemal beta dynein heavy chain 2. DNAH2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of DNAH2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
