Anti-RX antibodies enable researchers to detect and measure the RX antigen in biological samples. This target is a reported synonym of the RAX gene, which encodes retina and anterior neural fold homeobox. This protein is known to function in eye development and limb development, among other biological roles. The human version of RX has a canonical amino acid length of 346 residues and a protein mass of 36.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. Other names for this target antigen include MCOP3, MCOPS16, and RAX1. Indicated applications for RX antibodies listed below include ELISA and Western Blot.
