Recombinant Human Glutathione S-transferase Alpha 1

Cat. No.: GSTA1-489H
Product Overview: Recombinant human GSTA1 protein was expressed inE.coliand purified by using conventional chromatography techniques.
Description: GSTA1, also known as Glutathione S-transferase alpha 1, belongs to a glutathione S-transferase alpha class and is the most abundantly expressed in liver. This protein functions in the detoxification of electrophilic compounds, including carcinogens, therapeutic drugs, environmental toxins and products of oxidative stress, by conjugation with glutathione.

Form: Liquid. In 20 mM Tris-HCl buffer (pH8.0) containing 1mM DTT 10% glycerol
Molecular Weight: 25.6 kDa (222aa)
Purity: > 90% by SDS - PAGE
Concentration: 1 mg/ml (determined by Bradford assay)
Biological activity: Specific activity is 5-8 units/mg, and 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.
Activity Assay: 1.Prepare a 1.mll 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 the A340nm until the value is constant using a spectrophotometer. 3.Add 50ul of recombinant GSTA1 protein with various concentrations (1ug, 2ug, 5ug) in 950ul reaction buffer. 4.Mix by inversion and record the increase in A340nm for 5 minutes.
Storagee: Can be stored at +4°C short term (1-2 weeks). For long term storage, aliquot and store at -20°C or -70°C. Avoid repeated freezing and thawing cycles.
