Description
Principle of the assay: human Thioredoxin ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Thioredoxin has been precoated onto 96-well plates. Standards(E.coli, V2-V105) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Thioredoxin is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human Thioredoxin amount of sample captured in plate.
Background: Thioredoxin is a class of small redox proteins known to be present in all organisms. It is mapped to 9q31.3. Thioredoxins are proteins that act as antioxidants by facilitating the reduction of other proteins by cysteine thiol-disulfide exchange. They can also act as electron donors to peroxidases and ribonucleotide reductase. Thioredoxin is a 12-kD oxidoreductase enzyme containing a dithiol-disulfide active site. It plays a role in many important biological processes, including redox signaling. This gene also plays a central role in humans and is increasingly linked to medicine through their response to reactive oxygen species (ROS). VDUP1 is a key stress-responsive inhibitor of Thioredoxin activity in cardiomyocytes
