Synonyms Thioredoxin Reductase (NADPH), NTR, TrxR.
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.
Description Thioredoxin Reductase (NADPH) Yeast Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain having a molecular mass of 36 kDa.
Thioredoxin Reductase is purified by proprietary chromatographic techniques.
Source Escherichia Coli.
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation Each mg of protein contains 20mM phosphate buffer pH 7.4 and 0.15M sodium chloride.
Solubility It is recommended to reconstitute the lyophilized NTR in sterile 18MΩ-cm H2O.
Stability NTR although stable at 4℃ for 3 weeks, should be stored desiccated below -18℃.
Please prevent freeze thaw cycles.
