These FHR4 ELISA kits are immunodetection tools for measuring the levels of FHR4 in biological samples. FHR4 is an alias of the human CFHR4 gene, which encodes the protein, complement factor H related 4. The protein is known to be involved in complement regulation. The CFHR4 protein is 578 amino acid residues in length and 65.4 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is notably expressed by the liver and secreted in plasma. This protein is known to be glycosylated. Other names for this target antigen include CFHL4 and FHR-4.
