Abstract

This invention relates generally to the field of cell seperation. In particular, the invention provides processes for isolating a target cell, cellular organelle or virus from a sample, using inter alia, nonspecific binding between a target cell, cellular organelle or virus with a magnetic microbead modified to comprise hydroxyl, carboxyl or epoxy groups.
