Qbeads-NTA-Ni is designed for rapid purification of 6xHis-tagged proteins. Qbeads-NTA-Ni has nitrilo- triacetic acid (NTA) groups with charged nickel covalently bind to surface dextran of Qbeads. Due to the high affinity, Qbeads-NTA-Ni can be used for capturing 6xHis-tagged proteins. Bound 6xHis-tagged proteins can be temporarily immobilized under magnetic attraction, so the other parts in supernatant can be removed easily and efficiently. Bound proteins can be directly used in downstream applications or be eluted off the beads. The capacity of purified 6xHis-tagged proteins (~35kDa) captured by Qbeads-NTA-Ni is approximately 5 mg/mL.
