WebPurification of tagged proteins is performed using a bind–wash–elute procedure. Due to the high aniffity of the tag to an affinity purification matrix, high-purity proteins (up to 95% pure) are obtained in a single purification step. The Glutathione S-Transferase (GST) tag, His tag, and Strep-tag® II are the three most commonly used WebNi-NTA His•Bind Resin is used for rapid one-step purification of proteins containing a His•Tag® sequence by metal chelation chromatography. The His•Tag sequence binds to Ni2+ cations, which are immobilized on the Ni-NTA His•Bind Resin. After unbound proteins are washed away, the target protein is recovered by elution with imidazole.
