500 nm diameter magnetic beads with Amine (NH2) functionalized surface. Features: - Conjugation Ready: NH2 groups on the magnetic beads can be reacted with activated carboxyl groups to covalently load proteins, small molecules, or DNA / RNA onto the beads. - High monodispersity. - Stable in high salt conditions. - Fast response to a magnet. Applications: - Magnetic separation of DNA, RNA, proteins, antibodies, cells and small molecules from complex samples. - Carboxyl containing proteins, small molecules, DNA / RNA can be covalently attached to the amine groups on the bead surface through EDC/NHS reactions.
