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.

The biotin labelling of this antibody ensures strong and stable interaction with avidin or streptavidin, making it suitable for a wide range of downstream applications, including Western blotting and ELISA.

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.
