Notes: Thioredoxin 1 (Trx1) is a thiol-disulfide oxidoreductase and part of the antioxidant thioredoxin system that is involved in the maintenance of cellular thiol redox homeostasis.{57135,57136,57138} It is ubiquitously expressed, localizes primarily to the cytoplasm with some nuclear localization, and is upregulated in and released from cells under conditions of oxidative stress.{57135,57137,57136} Trx1 contains two active site cysteine residues at positions 32 and 35, with additional cysteines at positions 62, 69, and 73.{57136} Trx1 can be truncated to form Trx80 or Trx84, which contain 80 or 84 amino acids from the N-terminus of full-length Trx1, respectively.{58380,58379} Full-length Trx1 contains a KKGQK amino acid sequence between positions 79 and 84, and cleavage at the KK motif leads to the generation of Trx80, whereas cleavage at lysine 84 generates Trx84.{58379} Trx80 is secreted from a variety of cell types, including U937 monocytes, cytotrophoblasts, and CD4+ T cells, and has been found in human plasma.{54301} Unlike full-length Trx1, Trx80 is catalytically inactive and has pro-inflammatory, rather than anti-inflammatory, activity.{54300} Cayman's Thioredoxin 1 Truncated (human) Monoclonal Antibody (Clone 7D11) can be used for direct ELISA, sandwich ELISA, flow cytometry (FC), immunofluorescence (IF), immunoprecipitation (IP), and Western blot (WB) applications. The antibody recognizes Trx80 and Trx84, but not full-length Trx1, by ELISA. However, under denaturing conditions of SDS-PAGE, the antibody recognizes Trx80 and Trx84 at approximately 9 to 10 kDa but also detects full-length Trx1 at approximately 12 kDa.
