Abstract
Method for concentrating and collecting small quantities of fetal nucleated red blood cells contained in the maternal blood. The method for concentrating and collecting nucleated red blood cells from the maternal blood comprises: (i) subjecting the maternal blood to a first density-gradient centrifugation and collecting a cell fraction containing nucleated red blood cells; (ii) treating the cell fraction containing nucleated red blood cells so as to selectively changes the density of the nucleated red blood cells from that of the white blood cells; and (iii) subjecting the treated cell fraction containing the nucleated red blood cells to a second density-gradient centrifugation so as to collect a fraction containing nucleated red blood cells.
