A simple and rapid method for separation of cells is to functionalize magnetic particles with a receptor that selectively captures the target and then pull the magnetic particles out of the mixture upon applying a magnetic field The separation efficiency of magnetic separation …

Cell sorting - Wikipedia

Following cell separation, both MicroBeads and REAlease Biotin Complex can be gently removed, leaving the cells bead- and label-free for further cell separation steps. REAlease Technology allows for magnetic cell isolation by positive selection of target cells and subsequent removal of any beads and labels from the cells.
