GSTrap™ HP columns are prepacked with Glutathione Sepharose High Performance resin and provide high-resolution, one-step purifications of glutathione S-Transferase (GST) tagged proteins.

• High resolution purification of GST-tagged proteins.
• Mild elution conditions preserving protein antigenicity and function.
• Fast, one-step purification.
• Easy to use with syringe, pump or a chromatography system.

GSTrap™ HP 1-mL and 5-mL columns are prepacked with Glutathione Sepharose High Performance resin, which provides high-resolution purifications, thus a more concentrated sample. GST-tagged proteins are purified from pretreated bacterial lysates by affinity chromatography using immobilized glutathione, such as Glutathione Sepharose High Performance. GST-tagged proteins are bound to the affinity resin, and impurities are removed by washing with binding buffer
