[0002] A cell magnetic bead sorter is a laboratory device used for rapidly and efficiently sorting cells labeled with magnetic beads. This method is called magnetic bead sorting, which is a non-invasive and non-damaging cell sorting technique. The basic principle of magnetic bead sorting is to bind magnetic particles (magnetic beads) to specific markers (such as antibodies or proteins) on the surface of target cells (such as specific types of immune cells, stem cells, or cancer cells), and then use a magnetic field to separate the labeled cells from the unlabeled cells.
