Prometheus™ Ni-NTA Magnetic Agarose beads are for fast and easy, small scale His-tagged protein purification using magnets. They provide superior affinity, very low nonspecific binding, and offer the highest binding capacity of >75 mg His-tagged protein/ml gel. Prometheus™ Ni-NTA Magnetic Agarose beads are ideal for purification from dilute solutions and for working with protein pulldowns (IP) and Chromatin IP (ChIP) using native or denaturing conditions.
