Anti-TXNRD3 antibodies are used in the immunodetection of the protein thioredoxin reductase 3. In humans, the canonical protein has a reported length of 643 amino acid residues and a mass of 70.7 kDa. Its subcellular localization is in the nucleus, ER, and cytoplasm. A member of the Class-I pyridine nucleotide-disulfide oxidoreductase protein family, TXNRD3 is known to be involved with cell differentiation and spermatogenesis. Synonyms for this target antigen include selenoprotein TXNRD3, thioredoxin and glutathione reductase, thioredoxin glutathione reductase, thioredoxin reductase 2 intronic transcript 1, and TXNRD3 neighbor gene protein. TXNRD3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some TXNRD3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
