title: Rapid methods to visualize Y-specific repeated DNA sequences in cytological preparations.
abstract: We described rapid methods to detect Y-specific repeated DNA sequences in cytological preparations using in situ hybridization. A human Y chromosome specific DNA probe with an insert equivalent to that in pHY2.1 was labelled with [alpha-32P]dCTP or photobiotin, and hybridized to chromosome preparations. Signals were visualized specifically on Y chromosomes after 1 day's autoradiography or a couple of hours treatment with streptavidin alkaline phosphatase/BCIP/NBT. These methods are useful for molecular confirmation of Y-autosomal translocations.
