PurKine™ GST-Tag Purification system is based on innovative high-capacity matrix for convenient single-step purification of recombinant glutathione S-transferase (GST) fusion proteins and other glutathione binding proteins expressed in E. coli, insect cells and mammalian cells. The portfolio allow optimization of process for maximum protein yield, stability and solubility. Tests also confirm that no decrease in performance occurs after at least five repeated uses. The PurKine™ GST-Tag Purification resin is also available as prepacked spin column and kit formats.
