Recombinant Human Glutathione Reductase, His-tagged

• Cat.No.: GSR-1318H
• Product Overview: Recombinant human GSR protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Description: GSR is a member of the class-I pyridine nucleotide-disulfide oxidoreductase family. This enzyme is a homodimeric flavoprotein and plays a role in maintaining glutathione (GSH) in its reduced form by catalyzing the reduction of glutathione disulfide (GSSG): GSSG + NADPH + H+ ->2GSH + NADP+. In most eukaryotic cells, GSR maintains the ratio of [GSH]/[GSSG], and participates in several vital functions such as the detoxification of reactive oxygen species as well as protein and DNA biosynthesis.
• Form: Liquid. In 20 mM Tris-HCl buffer (pH 8.0) containing 1 mM DTT, 10% glycerol, 0.1 M NaCl.
• Molecular Weight: 54.3 kDa (504 aa) confirmed by MALDI-TOF
• Purity: > 95 % by SDS-PAGE
• Concentration: 1 mg/ml (determined by Bradford assay)
