  • Method and apparatus for magnetically separating selected particles, particularly biological cells
    Publication number: 20030062314
    Abstract: A method and apparatus for magnetically separating target particles of a selected type from a sample in order to produce a concentration of the target particles in the sample, or a depletion of the sample with respect to the target particles, by producing a sample mixture of the sample with magnetic particles having a selective affinity to magnetically stain the target particles; producing a flow of a buffer liquid through a tube which includes an inlet connectable to a source of buffer liquid, and an outlet for the buffer liquid; after a flow of the buffer liquid has been produced through the tube, introducing the sample mixture into the buffer liquid flowing through the tube such that the buffer liquid forms a continuous liquid carrier for the sample mixture as both are fed through the tube; and applying a magnetic field across the tube at a magnetizing station therein to cause the magnetically-stained target particles to be separated and retained in the buffer liquid within the tube at the magnetizing stat
