Ni-charged MagBeads

Description:

The GenScript Ni-charged MagBeads are developed for quick and efficient small-scale purification of polyhistidine-tagged proteins under native or denaturing conditions.

The GenScript Ni-Charged MagBeads are average 40µm in size, superparamagnetic beads with strong metal-chelating agent covalently bound to their surfaces. They are pre-charged with nickel and ready to use for quick and small-scale purification of polyhistidine-tagged proteins. The beads are supplied as 25% slurry in phosphate buffered saline (PBS), pH 7.4, containing 20% ethanol. The Ni-Charged MagBeads have a binding capacity of 5 to 20 mg 6×His-tagged protein per 1 ml settled beads (e.g. 4 ml 25% slurry).

Key Features:

  • Quick and convenient separation accomplished by magnetic force
  • High binding capacity with 5 - 20 mg of 6xHis-tagged protein/ml
  • Compatible with various reagents needed in the purification process(see table 1)
  • Resin can be regenerated for multiple uses
  • Extremely low nonspecific binding
