Cat#:RP-3546H;Product Name:Recombinant Human GST Protein;Synonym:Glutathione S-Transferase, GST, Glutathione S-transferase class-mu 28 kDa isozyme, GST 28, EC 2.5.1.18, Sj28GST, Sj28 antigen.;Description:Recombinant Glutathione S-Transferase full length protein (1-224a.a.) expressed in E.coli, having a molecular mass of 26kDa. GST was isolated from an E. coli strain that carries the coding sequence for Schistosoma japonicum GST under the control of a T7 promoter. The GST is purified by proprietary chromatographic techniques.;Source:E.coli;Purity:Greater than 95% as determined by SDS-PAGE.;Bioactivity:Specific activity is >20 units/mg. A unit is defined as the amount of enzyme that conjugate 1.0 u mole of 1-chloro-2,4-dinitrobenzene (CDNB) with reduced glutathione per minute at pH 6.5 at 25°C.;Formulation:GST supplied in Phosphate Buffered Saline pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Storage:Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.;
