The Hf ELISA kits listed below utilize specific antibodies for the plate-based assay of Hf in various samples. Hf is another term for the CFH gene, which encodes the protein, complement factor H in humans. It has been reported that Hf plays a role in proteolysis, among other functions. Structurally, the CFH protein is 1231 amino acid residues in length and 139.1 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is reported to be expressed in the retinal pigment epithelium. This protein is known to be sulfated and glycosylated. Other names for this target antigen include AHUS1, AMBP1, and ARMD4. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
