Anti-HUS antibodies are protein reagents that detect specific antigens. The HUS antigen is another term for the human protein complement factor H, encoded by the CFH gene. The protein is a reported glycoprotein that plays an essential role in maintaining a well-balanced immune response by modulating complement activation. Canonically, it has an amino acid length of 1231 residues and a mass of 139.1 kilodaltons. It is a secreted protein and it is reported to be expressed in the retinal pigment epithelium. Other alias names for HUS include AHUS1, AMBP1, and ARMD4. Western Blot is the most common application for the HUS antibodies listed below. ELISA and Immunohistochemistry are also common applications.
