Magnetic Beads Antibodies

Magnetic beads used in purification contain a magnetic core which is covered in different materials. They are typically either Ferrimagnetic, or superparamagnetic 3 (fig.2). 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.

Magnetic cell separation Cell separation Miltenyi

Immunomagnetic cell separation is based on antibodies coupled to magnetic beads. During incubation with a cell suspension, the antibody/bead complex binds to cells expressing the corresponding epitope. When the cell suspension is placed into a magnetic field, magnetically labeled cells are retained, while unlabeled cells can be removed.

2007-4-1  1. Introduction. The development of tumor-targeting antibody-conjugate nanoparticles (bioprobes) for alternating magnetic field (AMF) cancer therapy requires magnetic particles with a long circulation time in the blood, a high specific power absorption rate (SAR), an efficient in vivo tumor uptake and the possibility to detect the particles in blood and organs.
