The FR ELISA kits listed below utilize specific antibodies for the plate-based assay of FR in various samples. FR is another term for the SLC4A1 gene, which encodes the protein, solute carrier family 4 member 1 (Diego blood group) in humans. It has been reported that FR plays a role in the transport of ions, among other functions. Structurally, the SLC4A1 protein is 911 amino acid residues in length and 101.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is notably expressed in erythrocytes. This protein is known to be N-glycosylated and phosphorylated. Other names for this target antigen include AE1, AE1, and BND3.
