Introduction | Membrane-bound & Cytosolic forms of GST are encoded by 2 separate supergene families. These enzymes function in the detoxification of electrophilic compounds, including carcinogens, therapeutic drµgs, environmental toxins and products of oxidative stress, by conjµgation with glutathione. There are 8 different classes of soluble cytoplasmic mammalian GST: alpha, kappa, mu, omega, pi, sigma, theta and zeta. The GSTA1is found in a cluster mapped to chromosome 6, and is highly expressed in the liver. GSTA1 protects the cells from reactive oxygen species. |
Synonyms | GST2, GSTA1-1, GTH1, GSTA-1, GSTAI, GSTA-I, EC 2.5.1.18, Glutathione S-transferase A1, GST HA subunit 1, GST-epsilon, GST class-alpha member 1, GSTA1, MGC131939. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered colorless solution. |
Formulation | The GSTA1 solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 1mM DTT and 10% glycerol. |
Stability | 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 multiple freeze-thaw cycles. |
