FISH and PRINS, a strategy for rapid chromosome screening: application to the assessment of aneuploidy in human sperm

Abstract

The co-utilization of FISH and PRINS techniques for in situ chromosome screening was tested on human sperm nuclei. We used a centromeric repeat probe specific for chromosome 4 for FISH. PRINS reactions were performed with α-satellite primers specific for either chromosome 9 or chromosome 18. Double labeling was obtained and estimates of disomy rates were carried out for the three chromosomes.
