PtX™ Rabbit Anti-GST

Recombinant rabbit monoclonal antibody against native and denatured forms of glutathione S-transferase (GST). PtX™ Rabbit Anti-glutathione S-transferase antibody is produced in Nicotiana benthamiana plants and used in various immunoassays for the detection of purified GST and GST-tagged recombinant proteins.

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. The GST superfamily can be categorized into cytosolic, mitochondrial and microsomal GST subfamilies. GST-tags are often fused to target recombinant proteins to facilitate the purification and study of the target proteins by antibodies directed against the GST tags.

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.
