Do you have any solution stability information on glutathione peroxidase from erythrocytes?
The following information on the bovine source enzyme (equivalent to Product G6137) probably also applies to the human source enzyme (G4013). According to the literature, there is no appreciable loss after 3 months in the presence of 1 mM dithiothreitol (DTT) if solutions of the enzyme are frozen. There is a significant loss (15-22%) in 1 month when in the presence of 2 mM reduced glutathione (GSH), and if neither DTT nor GSH present, the loss is even greater (60-70% lost in 1 month frozen.1There are also stability concerns with the powdered form of Glutathione Peroxidase; the powder is shipped on dry ice and should be kept frozen. We have found that the powder should be stable at least a year if stored in the freezer below 0°C.In our experience, without DTT or mercaptoethanol present, a solution of Glutathione Peroxidase may lose much of its activity within a day, even on ice. Our general recommendation is to reconstitute in 10 mM sodium phosphate, pH 7.0 with at least 1 mM dithiothreitol. The solution should be divided into working aliquots and promptly frozen; it will be stable through one freeze-thaw cycle.1. Biochimica et Biophysica Acta, 358, 251-261 (1974).
