Listed are ELISA Kits for the detection of DAF1, an alias name of CD55 molecule (Cromer blood group). The human protein, encoded by the gene CD55, is 381 amino acid residues long and has a mass of 41,400 daltons. However, there are up to 7 reported isoforms. It is a member of the Receptors of complement activation (RCA) family. This protein is reported to have a membrane and secreted cellular localization, and is glycosylated. The gene is associated with Complement hyperactivation, angiopathic thrombosis, and protein-losing enteropathy. This target may also be known as: complement decay-accelerating factor, CD55 antigen, CD55 molecule decay accelerating factor for complement (Cromer blood group), Cromer blood group antigen, CROM, DAF, and TC.
