The ELISA kits listed below target DIO1, the symbol for the human gene, iodothyronine deiodinase 1, and a member of the Iodothyronine deiodinase family. The protein has an enzyme classification of thyroxine 5'-deiodinase. The protein encoded by DIO1 has a predicted amino acid length of 249 and a mass of 28.9 kDa. There are currently 9 reported isoforms. DIO1 may also be known by the following names: type 1 DI, thyroxine deiodinase type I (selenoprotein), iodothyronine deiodinase type 1, deiodinase iodothyronine type I, DIOI, and type I iodothyronine deiodinase, and 5DI. Orthologs of the gene, including human, mouse, rat, plant, and other mammalian are available targets of several ELISA kits.
