Purification Resins
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. If you want to learn more about the GST tag read our comprehensive guide.

Gluthathione MagBeads efficiency
Fig.1: Reliable lot-to-lot reproducibility. Glutathione-S-transferase was purified from E.coli lysates using three independent production lots of PureCube Glutathione MagBeads. FT: Flow through, E1-E5: Elution fractions.
Our GST-tag purification products are able to reproduce all purification assays from lot to lot. We achieved minimal fluctuations between multiple uses of our beads. Multiple consecutive GST-tag purification with the same beads from is ensured to be of the same high quality.
