  • Patent number: 7279277
    Abstract: A method for the identification of human foetal cell nuclei is provided wherein the method involves subjecting chromosomes of cell nuclei to exonucleolytic digestion by an enzyme so as to remove end regions of each chromosome; and detecting the presence of a DNA sequence remaining in foetal DNA but absent from maternal DNA as a result of the digestion process. Once identified, the foetal DNA can be subject to diagnosis for example to detect chromosomal abnormalities.
    Type: Grant
    Filed: April 20, 2001
    Date of Patent: October 9, 2007
    Assignee: Simeg Limited

  • Patent number: 7083924
    Abstract: A method for the identification of foetal DNA in a maternal DNA-containing sample such as a blood or vaginal sample, said method comprising (a) isolating DNA from said sample, (b) subjecting said DNA to exonucleolytic digestion by an enzyme so as to remove end regions of each DNA molecule, and (c) detecting the presence of a DNA sequence remaining in foetal DNA but absent form maternal DNA as a result of said digestion process. Once identified, the foetal DNA can be subject to diagnosis for example to detect chromosomal/DNA abnormalities, including in particular aneuploides such as foetal trisomy 21.
