Anti-KBTBD4 antibodies are used in the immunodetection of the protein kelch repeat and BTB domain containing 4. In humans, the canonical protein has a reported length of 518 amino acid residues and a mass of 58.1 kDa. Up to 2 different isoforms have been reported for this protein. Synonyms for this target antigen include BTB and kelch domain containing 4, BTB and kelch domain-containing protein 4, kelch repeat and BTB (POZ) domain containing 4, and kelch repeat and BTB domain-containing protein 4. KBTBD4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some KBTBD4 antibodies may have been used in research and have associated citations. Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
