TXNRD2 (Selenoprotein Z)

TXNRD2 (Thioredoxin reductase 2), also known as TRXR2, TR3, SELZ, or TR-BETA, Thioredoxin reductases, are selenocysteine (sec)-containing flavoenzymes that maintain thioredoxins, small proteins that catalyze redox reactions, in the reduced state using the reducing power of NADPH. By STS analysis and genomic sequence analysis, respectively, Miranda-Vizuete et al. (1999) and Sun et al. (1999) mapped the TXNRD2 gene to chromosome 22q11.2. Miranda-Vizuete et al. (1999) mapped the mouse gene to chromosome 16. Gasdaska et al. (1999) showed that TXNRD2 was a thioredoxin reductase that could directly reduce proteins such as insulin.\n\nUniProt Number:\nQ9NNW7\n\nGene ID:\nTXNRD2\n\nApplications:\nSuitable for use in Western Blot and Immunohistochemistry (Paraffin).\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Handling:\nStore at -20?C for one year. After reconstitution, store at 4?C for one month. Can also be aliquoted and stored frozen at -20?C for long term.\nAvoid repeated freezing and thawing. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
