Glutathione Sepharose High Performance is an affinity resin recommended for purifying glutathione S-transferase (GST)-tagged proteins when high resolution is the priority. Fast, one-step GST-tagged protein purification. The small bead size (34 µm) enables high-resolution purification of tagged proteins. Mild elution conditions preserve protein antigenicity and function. Resin for high-resolution purification of GST-tagged proteinsGlutathione Sepharose High Performance is used to purify GST-tagged proteins from bacterial lysates. The proteins are eluted under mild, non-denaturing conditions using reduced glutathione, which preserves protein antigenicity and function. On-column cleavage of the GST tagThe GST-tag can be cleaved with a protease while the protein is still bound to the affinity column. It eliminates the extra step of separating the released protein from the GST-tag.Properties of Glutathione Sepharose High Performance resinThe glutathione ligand is coupled via a 10-carbon linker to highly cross-linked 6% agarose, 34 µm beads. These features help to optimize purification that yields sharp peaks with concentrated proteins.Successful use in published researchResearch and applications using this GST resin include: Purification of p47phox variants to study a conformational mechanism that underlies the protein’s activationPurification of tagged proteins to evaluate the interaction between cellular RNA helicases and an antiviral proteinCompatible empty columnsCytiva's solutions include a variety of empty columns, Glutathione Sepharose High Performance resin is compatible with Tricorn, HiScale, and XK column lines.
