The human DIO2 selenocprotein is encoded by the DIO2 gene and catalyzes the conversion of prohormone thyroxine (3,5,3',5'-tetraiodothyronine, T4) to the bioactive thyroid hormone (3,5,3'-triiodothyronine, T3) by outer ring 5'-deiodination.
We provide the human DIO2 enzyme with approx. 20% Sec contents, mixed with inactive forms containing Sec-to-Lys and Sec-to-Gln substitutions, at more than 95% purity in aliquots at amounts from 50 to 500 µg.

• Genuine Sec-containing selenoproteins
• More than 95% purity
• No animals used as protein sources (grown in bacteria)
