PureCube Glutathione Agarose

The GST tag is a 26 kDa protein that binds to glutathione-coupled agarose resins. This tag is considerably larger than the His tag and is often chosen to promote recombinant protein folding. PureCube Glutathione Agarose is based on BioWorks Workbeads.

For purification from cell culture supernatants or pull-down experiments, we recommend PureCube Glutathione MagBeads. To detect GST-tagged proteins in Western Blot experiments, Cube Biotech offers a highly specific GST antibody.

GST-tagged protein purification with PureCube Glutathione Agarose

High protein binding capacity

In a comparative study with equivalent, market-leading resins, PureCube Glutathione Agarose proved to be a competitive alternative, exhibiting the same protein binding capacity. Figure 1 is an SDS-PAGE of GST purified on gravity columns packed with PureCube Glutathione Agarose and the equivalent resin from Competitor G. Both resins yielded up to 10 mg/mL protein. TL: total lysate; CL: cleared lysate; FT: flow-through; W1/W4: wash fractions; E1-E6: elution fractions.

Fig. 1: Purification yield is comparable to that of a market-leading resin.
