Ni-NTA Magnetic nano beads are silica beads, with an average diameter of 0.4 μm and a range of 0.2~0.8 μm diameter, that contain magnetic particles and have strongly metal-chelating nitrilotriacetic acid (NTA) groups covalently bound to their surfaces. They are precharged with nickel and ready to use for capturing 6xHis-tagged proteins under native conditions for protein expression screening programs, as well as smallscale purification of 6xHis-tagged proteins. Ni-NTA Magnetic nano Beads are supplied as a 10% (v/v) suspension with a binding capacity of 3 mg protein per ml of suspension for 6xHis-tagged DNA polymerase
Storage :
Ni-NTA Magnetic nano beads are supplied as a 10% (v/v) suspension in 20% ethanol and should be store at 2~8°C.
Flexible: The protocol may be carried out with a magnet or via centrifugation. Excellent performance: Highly pure proteins are obtained through our exclusive SSMB (Spherical-Shape Magnetic Beads). High purity and High yield: Average binding capacity of 500 μg protein per ml of suspension for 6xHis-tagged protein. Purity that is > 90%. Reproducibility: The only hands-on step is the addition of protein extract, maximizing reproducibility. Fast process: The entire purification is complete in about 30 minutes!
