Absolute Mag™ DNA Magnetic Particles, Silica-coated, 1.0 μm (#WHM-G180) are superparamagnetic particles with porous silica coating. These particles are designed for automatic DNA/RNA separation such as genomic DNA, plasmid DNA, total RNA and PCR products. DNA/RNA bind to these porous silica surface under high salts conditions (5 M guanidinium thiocyanate).
