The pGFLEX expression system allows production of target proteins fused to either the N or C terminus of the GST pi protein and provides rapid purification of target proteins as either GST fusions or native proteins after cleavage with thrombin.

High level of expression in E. coli, cos and other mammalian cultured cell lines.
