Anti-FNBP4 antibodies are used in the immunodetection of the protein formin binding protein 4. In humans, the canonical protein has a reported length of 1017 amino acid residues and a mass of 110.3 kDa. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the eye. Synonyms for this target antigen include FBP30 and formin-binding protein 30. FNBP4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the FNBP4 antibodies listed below. In addition, Immunocytochemistry is also a common application.
