About GST

Glutathione S-Transferase (GST) from Schistosoma japonicum is a 220 aa (about 26 kDa) protein, which is commonly used as a protein tag for immunoprecipitation and affinity purification. GST may increase the solubility and expression level of the fusion protein (so-called solubilization tag). Furthermore, GST-tagged fusion proteins are used in protein-protein interaction assays. Applications require highly specific tools to isolate GST-fusion proteins.
