The KN ELISA kits listed below utilize specific antibodies for the plate-based assay of KN in various samples. KN is another term for the CR1 gene, which encodes the protein, complement C3b/C4b receptor 1 (Knops blood group) in humans. Structurally, the CR1 protein is described to be 2039 amino acid residues in length and 223.7 kilodaltons in mass. It is localized to the membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include C3BR, C4BR, and CD35.
