  • Publication number: 20130331284
    Abstract: The present invention relates to enrichment and/or identification of fetal cells of a maternal blood sample using fetal cell specific ligands and/or fetal cell specific hybridization probes wherein the ligand or probes are directed to an endothelial/mesenchymal marker, e.g. CD105, CD146 or CD141, in a first round of enrichment and the ligand or probes, in a second round of enrichment, are directed to an epithelial marker, e.g. a cytokeratin, such as CK7, CK8, CK18 or CK19. Enriched or identified fetal cells may be subjected to steps of detection or diagnosis, wherefore the present invention enables non-invasive 5 prenatal diagnostics.

  • Publication number: 20120070827
    Abstract: The present application relates to methods for identification of foetal cells and generation and isolation of binding members recognising foetal cells. Said methods may further be used for other purposes relating to characterisation of biological samples and biological antigens. The methods are characterised by the applicability in situations where the interesting objects are present in a limited amount, or where the interesting objects are intermixed with other material, thus the methods are suitable for use in situations where the ratio of the interesting material compared to other material is low. The application discloses methods for use of detecting foetal cells and method of generating/isolating binding members towards antigenic material of low abundancy.

  • Publication number: 20110244462
    Abstract: Knowledge about telomere length is highly relevant in cancer and age related research. Currently applied methods for determining telomere length are subject to several drawbacks preventing fast and reliable information concerning telomere length. The present invention relates to a method for determining telomere length which is fast and reliable. The method is PCR based and may advantageously be performed in a “one tube system”, whereby time consuming and inconvenient handling steps are avoided. The method comprises annealing of up- and downstream tags to telomere fragments and subsequent PCR amplification of telomere fragments using primers having a sequence complementary or identical to at least part of the up- and downstream oligonucleotide tags.
