Immunomagnetic Separation is a laboratory technique used to isolate specific cells or particles from a mixture. It employs magnetic beads coated with antibodies that bind to target cells. When a magnetic field is applied, the beads, along with the attached cells, are pulled to one side, allowing for the separation of the desired components from the rest of the sample. This method is particularly useful in fields like clinical diagnostics and biotechnology, where it helps in purifying cells for research or therapeutic purposes. By selectively isolating target cells, researchers can study their properties or use them in various applications, such as cell therapy.
