http://www.cd-bioparticles.com/p/Protein-A-Magnetic-Particles_20_194_233_254.htmlAbsolute Mag™ Protein A Magnetic Particles, Cross-linked (# WHM-S087) are coated with cross-linked polymer on the surfaces of iron oxide crystals to render them resistant to common organic solvents. Large surface area combined with higher magnetite content (~15%) make them ideal solid phase for use in nucleic acid isolation, protein purification, immunology, and cell separations, especially used for the immunomagnetic separation (IMS) and real-time PCR to detect Escherichia coli. Otherwise, they are available impregnated with fluorophores for flow cytometry or easy bead location identification in phagocytosis assays.DNA/RNA Purification, Antibody/Protein Purification, Cell Isolation
