[Rapid detection of chromosomes X and Y using dual-color primed in situ labeling technique].
OBJECTIVE
To develop a rapid method for detection of chromosomes, and to present a feasible method for rapid detection of the interphase nuclei of uncultured amniocytes using modified dual-color primed in situ labeling (PRINS) technique.


METHODS
Chromosomes X and Y were detected and analyzed by the modified dual-color PRINS in 205 amniotic fluid samples.


RESULTS
The specific chromosomes were obtained on both metaphase and interphase nuclei. In more than 98% of the samples PRINS reactions with primers X and Y were successfully induced. One sample was properly identified and correctly scored as 47, XXY.


CONCLUSIONS
The results suggest that PRINS technique is rapid, simple and cost-effective. It is also sensitive and specific, and thus useful for rapid detection of chromosome abnormalities.
