<p>The present invention relates to separation of X- and Y-sperm cells from each other by centrifugation in a colloidal density medium. In the method X and Y sperm cells can be separated from each other in a medium formula which has a density close to that of X and Y sperm cells of the species in question. The method is simple and rapid and provides highly purified X and Y sperm cells, respectively in high yield.</p> |
