Glutathione S-transferase (GST) is a detoxification enzyme which catalyses the conjugation of the reduced form of glutathione to hydrophobic and electrophilic compounds of xenobiotic substrates, thereby protecting the host against toxic foreign chemicals and oxidative stress. Anti-GST antibodies are used in a variety of research applications, primarily in protein biochemistry and molecular biology. GST is a commonly used protein fusion tag that is added to recombinant proteins to facilitate their expression, purification, and detection. Anti-GST antibodies are used to detect the presence of the GST-tagged proteins and to isolate them from complex protein mixtures. GST-tagged proteins can be purified from crude lysates using affinity chromatography, whereafter the presence of the GST-tagged protein can be confirmed by western blotting using anti-GST antibodies. This technique is widely used in protein biochemistry and structural biology to isolate and study individual proteins or protein complexes. In addition, anti-GST antibodies are used in a variety of assays to detect the expression and localization of GST-tagged proteins in cells.

PtX™ | Plant-Based Expression

The biotechnology behind the development and manufacture of this product, transient plant-based expression, effectively turns Nicotiana benthamiana plants into single use, biodegradable bioreactors. Infiltrating this plant species with Agrobacterium tumefaciens cells, transformed with our proprietary plant expression vectors, allows rapid production of a wide variety of recombinant proteins. Plants are harvested and proteins extracted by various stages of filtration, clarification, purification, and polishing – resulting in a highly functional final product.
