http://www.cd-bioparticles.com/p/Protein-G-Magnetic-Particles_20_194_234_594.htmlAbsolute Mag Protein G Magnetic Particles, 50 nm (# WHM-X033) offer easy affinity isolation or handling of IgG without columns or centrifugation. The beads are uniform and superparamagnetic particles with a monolayer of recombinant protein G covalently coupled to the surface. Instead of blocking the surface of magnetic particles with BSA or other biocompatible polymers after the coating of protein G, these magnetic particles are reblocked with biocompatible polymers with significantly low non-specific binding.Antibody/Protein Purification, Cell Isolation, Immunoprecipitation
