Abstract
A non-invasive, risk-free method of prenatal diagnosis is provided. According to the method of the present invention transcervical specimens are subjected to trophoblast-specific immuno-staining followed by FISH, PRINS, Q-FISH and/or MCB analyses and/or other DNA-based genetic analysis in order to determine fetal gender and/or identify chromosomal and/or DNA abnormalities in a fetus. Also provided is a method of in situ chromosomal, DNA and/or RNA analysis of a prestained specimen by incubating the prestained specimen in ammonium hydroxide. Also provided is a method of identifying embryonic cells according to a nucleus/cytoplasm ratio of at least 1:1 and the presence of at least variably condensed chromatin.
