Does each Concanavalin A Magnetic Bead bind to one cell or multiple cells?

The average diameter of each Concanavalin A bead particle is ~1.0µm while the size range of a cell is 0.1-100 µm (the most commonly used cell lines like HeLa, HepG2 and HEK293 all have a cell size > 10µm). Therefore, in most cases, a cell is coated by multiple beads. This has also been confirmed by inspection under a microscope.
