GenScript Rabbit Anti-GST-tag Polyclonal Antibody is highly purified from rabbit antiserum by immunoaffinity chromatography. The immunogen used is a recombinant version of glutathione-S-transferase from Schistosoma japonicum. Glutathione-S-transferase is an epitope tag in generating fusion proteins. Antibodies specific to fusion proteins are useful in monitoring protein expression in Western Blots as well as immunoaffinity purification of proteins expressed in E. coli. The glutathione-S-transferases are a family of enzymes that catalyze the addition of the tripeptide glutathione to endogenous and xenobiotic substrates which have electrophilic functional groups. They play an important role in the detoxication and metabolism of many xenobiotic and endobiotic compounds. The glutathione adducts produced have increased solubility in water and are subsequently enzymatically degraded to mercapturates and excreted.
The antibody is stable for 2-3 weeks if stored at 2-8°C. For long term storage, aliquot and store at -20°C or below. Avoid repeated freezing and thawing cycles.
This antibody can be used to detect GST-fusion proteins in almost expression systems including bacterial expression system, mammalian expression system
and other systems.
