Title METHOD FOR COLLECTION OF NUCLEATED RED BLOOD CELLS BY DENSITY-GRADIENT CENTRIFUGATION UTILIZING CHANGE IN DENSITY OF BLOOD CELLS
Abstract Provided is a method for concentrating and collecting fetus-derived nucleated red blood cells contained in a small amount in the blood of a mother body. A method for concentrating and collecting nucleated red blood cells from the blood of a mother body, comprising (i) subjecting the blood of the mother body to first density-gradient centrifugation to collect a cell fraction containing the nucleated red blood cells, (ii) treating the cell fraction containing the nucleated red blood cells in such a manner that the density of the nucleated red blood cells can be varied in a selective manner, thereby avoiding the overlapping of the density of the nucleated red blood cells and the density of white blood cells each other, and (iii) subjecting the treated cell fraction containing the nucleated red blood cells to second density-gradient centrifugation to collect a fraction containing the nucleated red blood cells.
