6xHistidine and Glutathione S-transferase (GST) are commonly used protein/peptide tags added to the end of a recombinant protein to aid in their purification or detection. GenScript Ni-Charged MagBeads and Glutathione MagBeads provide simple, rapid and reliable methods for micro-scale purification of His- and GST-tagged fusion proteins from crude cell lysate prepared from bacteria, yeast or mammalian cell culture.

Ni-charged or Glutathione MagBeads Workflow

The Ni-Charged MagBeads are pre-charged with nickel and ready to use for micro-scale purification of 6xHis-tagged proteins under native or denaturing conditions. The Glutathione MagBeads are immobilized with Glutathione mainly through its central carbon on the beads surface for efficient GST binding. Read More »
