Amine magnetic particles are magnetic beads coated with a high density of amine functional groups on the surface. Magnetic beads surface functionalized with amine groups can be modified with heterobifunctional linker molecules and further reacted with ligands. Amine magnetic particles have shown important value in many applications, such as covalent binding of proteins, antibodies or other molecules, etc. CD Bioparticles are the leading manufacturer and supplier of Amine Magnetic Particles for R&D and commercialization in a wide variety of application areas.
