Abstract
A method for separating cells is presented. The method provides a flow through fractional cell sorting process that is based on the application of a magnetic force to cells having a range of magnetic labeling densities. Magnetically labeled cells are introduced into a flow channel. The cells are continuously fractionated into flow streams based on magnetic susceptibility by subjecting the cells in the flow channel to a magnetic field. The fractionated cells are recovered based on their response to the magnetic field. Methods employing dipole fractional sorters and quadrapole annular sorters are also presented.
