FlammaBead® Magnetic, hydroxyl is a magnetic nanoparticle that can be utilized in a wide range of biological and biomedical applications such as cell separation, antigen detection, DNA extraction, protein purification, etc. The surface of the particle is coated with hydrophilic silica, and hydroxyl groups are displayed. FlammaBead® Magnetic beads exert strong magnetism and display excellent dispersion ability, which enable to perform the fast binding and the excellent separation of target molecules. The relatively small particle size (200 ~ 300 nm) affords a large surface area that increase the binding capacity.
