GSTM1 protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.
实验流程
Prepare a 1 mL reaction mix into a suitable container: The final concentrations are 97 mM potassium phosphate, 0.97 mM EDTA, 2.5 mM glutathione, reduced, 1.0 mM 1-chloro-2,4-dinitrobenzene (CDNB), 3.2 % (v/v) ethanol. 2. Equilibrate to 25 °C and monitor at A340 nm until the value is constant using a spectrophotometer. 3. Add 50 µL of recombinant mouse GSTM1 protein with various concentrations (1 µg, 1 µg, 1 µg) in 950 µL reaction buffer. 4. Mix by inversion and record the increase at A340 nm for 5 minutes.

背景
GSTM1 is a glutathione S-transferase that belongs to the mu class. This enzyme acts by catalyzing the reaction of glutathione with an acceptor molecule to form an S-substituted glutathione (S=sulfur). The reactions utilizing glutathione contribute the transformation of a wide variety of electrophiles, including reactive products of lipid, protein, carcinogens, therapeutic drugs, environmental toxins, and products of oxidative stress. Recombinant GSTM1 protein was expressed in E. coli and purified by using conventional chromatography techniques.
