Abstract: A method for automatic sampling of immune cells from a biological fluid sample, e.g., whole blood, deposited in a well of a microwell plate. The sample contains red blood cells (RBCs) and magnetic beads which are designed to bind to the RBCs. The microwell plate is placed on a shaker having a magnetic adapter including at least one magnet. The magnet causes the RBCs bound to the magnetic beads to be attracted to and migrate to a wall of the well (e.g., the bottom or side wall) and be held against the wall. The shaker is then operated to shake the microwell plate in a manner and for a time period so as to suspend substantially evenly or homogeneously the immune cells in the biological fluid sample within a region of the well but still retain the holding of the RBCs to the wall of the well such that the immune cells are substantially isolated from the RBCs in the region of the well.
