Anti-RH4 antibodies enable researchers to detect and measure the RH4 antigen in biological samples. This target is a reported synonym of the RHCE gene, which encodes Rh blood group CcEe antigens. This protein is believed to be part of an oligomeric complex which is likely to have a transport or channel function in the erythrocyte membrane. The human version of RH4 has a canonical amino acid length of 417 residues and a protein mass of 45.6 kilodaltons, although 14 isoforms have been identified. It is reported to be localized in the membrane of cells and notably expressed in the bone marrow. RH4 is a member of the Ammonium transporter (TC 2.A.49) protein family. Indicated applications for RH4 antibodies listed below include ELISA and Western Blot.
