  • Patent number: 9429520
    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.

  • Patent number: 8945828
    Abstract: The present application relates to methods for identification of foetal cells and generation and isolation of binding members recognizing foetal cells. The methods of the invention may further be used for other purposes relating to characterization of biological samples and biological antigens. The methods are characterized 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.

  • 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.
