Anti-TrxR1 antibodies enable researchers to detect and measure the TrxR1 antigen in biological samples. This target is a reported synonym of the TXNRD1 gene, which encodes thioredoxin reductase 1. This protein is known to function in cell proliferation and signal transduction pathways, among other biological roles. The human version of TrxR1 has a canonical amino acid length of 649 residues and a protein mass of 70.9 kilodaltons, although 7 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include GRIM-12, TR, and TR1. Some TrxR1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
