    • The method of the present invention relates to a rapid procedure for detecting DNA in a cell, while preserving the morphology of the nucleus for analysis. The method comprises depositing a cell onto a polymeric membrane filter wherein the DNA contained in the cell is retained on the polymeric membrane filter and is available for binding with a fluorescently labeled nucleic acid probe, incubating the polymeric membrane filter with the labeled nucleic acid probe, and detecting the labeled nucleic acid probe wherein detection of the nucleic acid probe is indicative of the presence of the DNA. There are no separate permeabilization steps needed to permit the probes to enter the cell and hybridize to the DNA. The method is simple and quick and is applicable to the sample volumes found in clinical laboratories. The method of the present invention allows for analysis with single copy sequence probes of cells sorted onto, filtered onto, grown on or settled onto polymeric membrane filters. In addition, the method allows for the hybridization of probes containing single copy or repetitive DNA sequences to metaphase chromosomes as well as to interphase nuclei on membrane filters.
    • 本发明的方法涉及用于检测细胞中DNA的快速方法,同时保留用于分析的细胞核的形态。 该方法包括将细胞沉积在聚合物膜过滤器上,其中包含在细胞中的DNA保留在聚合物膜过滤器上,并且可用于与荧光标记的核酸探针结合,将聚合物膜过滤器与标记的核酸探针, 并检测标记的核酸探针,其中核酸探针的检测指示DNA的存在。 不需要单独的透化步骤来允许探针进入细胞并与DNA杂交。 该方法简便快捷,适用于临床实验室的样品量。 本发明的方法允许用分选到,过滤到,生长在或沉积在聚合物膜过滤器上的细胞的单拷贝序列探针进行分析。 此外,该方法允许将含有单拷贝或重复DNA序列的探针杂交到中期染色体以及膜过滤器上的间期核。
