The GPA ELISA kits listed below utilize specific antibodies for the plate-based assay of GPA in various samples. GPA is another term for the GYPA gene, which encodes the protein, glycophorin A (MNS blood group) in humans. Structurally, the GYPA protein is 150 amino acid residues in length and 16.3 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include CD235a and GPErik.
