Unit Definition
One unit equals the change in absorbance at 412 nm per minute at 25°C using 0.2 mM NADPH containing 5 mM DTNB (pH 7.0)
Stability
NTR although stable at 4°C for 3 weeks, should be stored desiccated below -18°C. Please prevent freeze thaw cycles.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
It is recommended to reconstitute the lyophilized NTR in sterile 18 MΩ-cm H2O.
Formulation
Each mg of protein contains 20 mM phosphate buffer pH 7.4 and 0.15 M sodium chloride.
Introduction
Thioredoxin reductase (TrxR/NTR), an enzyme belonging to the flavoprotein family of pyridine nucleotide-disulfide oxidoreductases. Thioredoxin reductase (TrxR), a component of the thioredoxin system, including thioredoxin (Trx) and NADPH, catalyzes the transfer of electrons from NADPH to Trx, acts as a reductant of disulfide-containing proteins and participates in the defense system against oxidative stresses.
Biological Activity
The specific activity was found to be 5 IU/mg.
