Absolute Mag™ HPTA Magnetic Particles, 0.75 µm


Absolute Mag™ HPTA Magnetic Particles, 0.75 µm (# WHM-C022) are aqueous dispersion of magnetic silica particles containing 2 hydoxypropyl trimethylammoniumchlorid (HPTA). They are reversibly to charged groups of biomolecules and can be eluted with salt- or pH-gradient. This superparamagnetic particles are widely used as strong anion exchanger. Anion-exchange magnetic particles bind selectively to the negatively charged membrane groups of cells, bacteria or viruses which can be separated by magnetic forces.
