Thyroxine 5-deiodinase (Dio3), partial (170:U->missing), rat, recombinant

Organism: Rattus norvegicus (Rat). Source: E.coli. Expression Region: 63-304aa(170:U->missing). Protein Length: Extracellular Domain. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: DFLCIRKHFL RRRHPDHPEP EVELNSEGEE MPPDDPPICV SDDNRLCTLA SLKAVWHGQK LDFFKQAHEG GPAPNSEVVR PDGFQSQRIL DYAQGTRPLV LNFGSCTPPF MARMSAFQRL VTKYQRDVDF LIIYIEEAHP SDGWVTTDSP YVIPQHRSLE DRVSAARVLQ QGAPGCALVL DTMANSSSSA YGAYFERLYV IQSGTIMYQG GRGPDGYQVS ELRTWLERYD EQLHGTRPRR L. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Responsible for the deiodination of T4 (3,5,3',5'-tetraiodothyronine) into RT3 (3,3',5'-triiodothyronine) and of T3 (3,5,3'-triiodothyronine) into T2 (3,3'-diiodothyronine). RT3 and T2 are inactive metabolites. May play a role in preventing prature exposure of developing fetal tissues to adult levels of thyroid hormones. Can regulate circulating fetal thyroid hormone concentrations throughout gestation. Essential role for regulation of thyroid hormone inactivation during bryological development.
