Target Details for TXN

Target: TXN (Thioredoxin (TXN))

Alternative Name: Thioredoxin-1

Background:

Gene Symbols: TXN, TRDX, TRX, TRX1

Background: The Oxidated Thioredoxin-1 ELISA Kit uses the "biotin probes" method to biotin label carbonyl groups of oxidized proteins. In this method, the biotin probes first react with carbonyl groups of oxidized proteins to form unstable Schiff bases, which are then further reduced to more stable amines. The biotinylated proteins can then be detected by ELISA. An anti-pan Thioredoxin-1 antibody has been coated onto a 96-well plate. Biotinylated samples are pipetted into the wells, and Thioredoxin-1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and HRP-conjugated streptavidin is used to detect oxidated Thioredoxin-1. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of oxidated Thioredoxin-1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
