Anti-Fe-ARD antibodies enable researchers to detect and measure the Fe-ARD antigen in biological samples. This target is a reported synonym of the ADI1 gene, which encodes acireductone dioxygenase 1. This protein is known to function in metabolic processes, among other biological roles. The human version of Fe-ARD has a canonical amino acid length of 179 residues and a protein mass of 21.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include APL1, APL1, and ARD.
