  • Sperm suspensions for sorting into X or Y chromosome-bearing enriched populations
    Patent number: 7838210
    Abstract: Sperm cell suspensions comprising a motility inhibitor are disclosed. The cells contained in such suspensions tend to have a greater capacity for enduring the various process steps typically associated with the sorting of sperm cells into gender enriched populations, thereby resulting in post-sort compositions with an increased number of viable or motile sperm. Processes for forming such cell suspensions, as well as processes for staining sperm cells, are also disclosed.
