ABSTRACT:
The present invention relates to methods of enriching for desired cell population from cell sources, such as body fluids, dispersed tissue specimens and cultured cells. In particular, the present invention relates to the use of a cell-trap centrifugation tube containing a specific density gradient solution adjusted to the specific density of a desired cell population to enrich for the desired cell from a cell source. The tube allows the desired cell population to be collected by decantation after centrifugation to minimize cell loss and maximize efficiency. In addition, the method can be further simplified by density-adjusted cell sorting which uses cell type-specific binding agents such as antibodies and lectins linked to carrier particles to impart a different density to the undesired populations in a more convenient manner. The rapid cell enrichment method described herein has a wide range of diagnostic and therapeutic applications.
