Function

Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (PubMed:17182577, PubMed:19032234, PubMed:2176490). Plays a role in the reversible S-nitrosylation of cysteine residues in target proteins, and thereby contributes to the response to intracellular nitric oxide. Nitrosylates the active site Cys of CASP3 in response to nitric oxide (NO), and thereby inhibits caspase-3 activity (PubMed:16408020, PubMed:17606900). Induces the FOS/JUN AP-1 DNA-binding activity in ionizing radiation (IR) cells through its oxidation/reduction status and stimulates AP-1 transcriptional activity (PubMed:11118054, PubMed:9108029). ADF augments the expression of the interleukin-2 receptor TAC (IL2R/P55).

Notes

Human Thioredoxin / TRX Antibody Pair - BSA and Azide free (ab308565) is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify human Thioredoxin / TRX in sandwich ELISAs and many other pair-based applications.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

The pair can be used in variety of assays and platforms including but not limited to:

  • Sandwich ELISA
  • FRET/TR-FRET/HTRF
  • Meso Scale Discovery® (MSD®)
  • Bead-based assays
  • AlphaLISA®/AlphaScreen®
  • DELFIA® immunoassays
  • Simoa® and Single Molecule Counting (SMC™) immunoassays
  • Multiplex

Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:

  • Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
  • Concentration of ~1 mg/ml as measured by the protein A280 method.

We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.

Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.

Please note:

The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.

The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.

We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Antibody properties:

Capture antibody: recombinant rabbit monoclonal (unconjugated) – 100 µg

Detector antibody: recombinant rabbit monoclonal (unconjugated) - 100 µg

Concentration: ~1 mg/ml

Storage buffer: 100% PBS

Activity summary

Thioredoxin (TRX) also known as TXN or Trx is a small redox protein with a molecular mass of approximately 12 kDa. It acts as an oxidoreductase enzyme facilitating the reduction of other proteins by cysteine thiol-disulfide exchange. Thioredoxin is ubiquitously expressed across various tissues indicating its function in a broad range of cellular activities. The protein comprises an active site with a conserved Cys-Gly-Pro-Cys sequence critical for its reducing activity.

Biological function summary

Thioredoxin influences cellular redox homeostasis and plays direct roles in regulating cell growth and apoptosis. It participates as a major reductant in cells influencing transcription factors and enzymatic activities that depend on thiol-disulfide exchanges. Thioredoxin can interact with other components like thioredoxin reductase and NADPH to form the thioredoxin system a powerful antioxidant defense mechanism. Diseases typically arise from abnormal regulation of this system highlighting its influence on cellular survival and proliferation.

Pathways

Thioredoxin integrates into significant signaling and metabolic processes. It is an important player in the cellular response to oxidative stress and participates in signaling pathways such as the MAPK and apoptosis pathways. In these pathways thioredoxin reduces the oxidative stress transcription factor AP-1 influencing cell fate decisions. Its interaction with thioredoxin-interacting protein (TXNIP) further modulates cellular responses to oxidative environments.

Associated diseases and disorders

Altered thioredoxin activity associates with cancer and neurodegenerative diseases. Its overexpression links to tumor progression where it promotes survival and resistance to apoptosis. Additionally in the context of neurodegenerative disorders thioredoxin’s interaction with amyloid-beta peptides implicates it in Alzheimer’s disease by mitigating oxidative stress damage. Through these conditions its role as a protector against oxidative stress remains pivotal.
