Anti-CFHR3 antibodies are used in the immunodetection of the protein complement factor H related 3. In humans, the canonical protein has a reported length of 330 amino acid residues and a mass of 37.3 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is notably expressed by the liver and secreted in plasma. CFHR3 is known to be a might be involved in complement regulation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include DOWN16, FHR-3, FHR3, HLF4, complement factor H-related protein 3, H factor-like 4, H factor-like protein 3, and CFHL3. A number of CFHR3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
