Used in research settings to quantify levels of the truncated form of thioredoxin (Trx80) in human biological samples such as serum, plasma, or cell lysates. This kit enables scientists to study the role of Trx80 in redox regulation, inflammation, and immune response. It is particularly useful in investigations related to oxidative stress-associated diseases including cardiovascular disorders, neurodegenerative conditions, and autoimmune diseases. The assay supports biomarker discovery and evaluation of therapeutic interventions targeting redox pathways.
