The process involves several key steps: 1. Magnetic Beads Coating: Magnetic beads are coated with antibodies that target specific antigens present on the cells or molecules of interest. 2. Incubation: The sample is mixed with the antibody-coated beads, allowing the target cells or molecules to bind to the beads. 3. Separation: A magnetic field is applied to separate the bead-bound target from the rest of the sample. 4. Washing: Unbound components are washed away, leaving only the purified target for further analysis.
