General description
The Thioredoxin Reductase Assay Kit uses a colorimetric assay for the determination of thioredoxin reductase activity in mammalian cells and tissues. It is based on the reduction of 5,5′-dithiobis(2-nitrobenzoic) acid (DTNB) with NADPH to 5-thio-2-nitrobenzoic acid (TNB) that produces a strong yellow color that is measured at 412 nm.
DTNB + NADPH + H+ ↔ 2 TNB + NADP+
Application
Using post nuclear extracts of rat liver, the kit shows linearity up to 0.25 units per mL. In this preparation, ~20% of the activity is due to non-specific reductase activity (refractory to the TrxR inhibitor).
Features and Benefits
