Abstract
A system for separating nucleated cells from a blood sample includes a charge-flow separator (CFS), which separates blood into fractions according to the surface charge density characteristics coupled with an affinity-filtration separator which either outputs a separated blood fraction to the CFS or receives a separated blood fraction from the CFS. The system permits separation of nucleated fetal red blood cells, erythroid progenitor cells and other nucleated cells found in blood samples.
