荧光原位杂交技术(fluorescence in situ hybridization,FISH)是20世纪80年代末期发展起来细胞遗传学与分子生物学相结合的一种新技术,应用在绒毛、羊水细胞染色体和不经培养的间期细胞检测,准确、快速做出产前诊断。本研究用我们建立的一片二区(或三区)FISH分析法,选用X、Y、1
Fluorescence in situ hybridization (FISH) is a new technique combining cytogenetics and molecular biology developed in the end of 1980s. It is applied in chorion, amniotic fluid chromosome and non-cultured interphase Cell detection, accurate and rapid prenatal diagnosis. In this study, we established a piece of two (or three districts) FISH analysis, the choice of X, Y, 1
