  • MACS® Cell SeparationMiltenyi Biotec

    Technology relies on recombinantly engineered antibody fragments instead of antibodies to label specific cell surface markers. The antibody fragments have a low affinity for cell surface epitopes. However when the fragments are multimerized as a complex they bind epitopes with high avidity and enable effective magnetic cell separation.

  • Magnetic BeadsAntibodies

    Ferrimagnetic magnetic cores are with over 30 nm relatively large with a strong magnetic moment. They retain this magnetic moment even after removal of the magnetic field. The strong magnetic field leads to a fast separation of the beads in the magnetic field. Possible downfalls are self-magnetism and unwanted attachment to metal surfaces.
