GST-Tag Affinity Resins & MagBeads

The GST-tag is a 26 kDA sized protein tag that can be used for protein purification. GST is short for Glutathione-S-Transferase. Using the GST-tag for protein purification is taking advantage of an enzyme's specificity to a substrate to gain maximum purity. Our GST-tag purification products offer great reproducibility for all purification assays. We achieved minimal fluctuations between numerous uses of our beads. A multiple consecutive GST tag purification with the same beads is ensured to be of the same high quality.
