A specific amplification of fetal DNA sequences from maternal sources - fetus is mixed

摘要

The present invention, the fetus is mixed - provides a method of selectively amplifying a fetal DNA sequence from maternal sources. From the DNA mixture containing a high proportion of non-trophoblast / fetal DNA, the method takes advantage of the differential methylation to allow selective amplification of trophoblast / fetus array. The present invention provides a fetal DNA sequences amplified, have uses for aneuploidy detection.
