ABSTRACT:
The present invention is related to a method for separating a first population of cells from a second population of cells in a sample by discontinuous density gradient separation using dense particles to target the first population of cells and a density separation medium (DSM) that is at least about 0.001 g/cm3higher than the density of the second population of cells.
