Abstract:
1. A method of sorting a mixture of stained sperm cells having either characteristic A or characteristic B into at least one population, the method comprising the steps of: a. flowing a fluid stream containing stained sperm cells through a flow path at a fluid delivery rate; b. exciting fluorescence emissions from the stained sperm cells having characteristic A and the stained sperm cells having characteristic B flowing in the flow path; c. detecting the fluorescence emissions from the excited sperm cells; d. classifying the stained sperm cells as either having characteristic A or having characteristic B based upon the fluorescence emissions; e. selecting stained sperm cells in the flow path based on their classification; and f. photo-damaging the selected sperm cells to produce an enriched population of sperm with respect to either characteristic A or characteristic B.
