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.

Overview of Cube Biotech's Glutathione products for GST tag protein purification.


Usage Specific binding and purification of GST-tagged proteins

PureCube Gluathione MagBead's efficiency

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.
