  • Patent number: 12409457
    Abstract: The invention features devices and methods for the deterministic separation of particles. Exemplary methods include the enrichment of a sample in a desired particle or the alteration of a desired particle in the device. The devices and methods are advantageously employed to enrich for rare cells, e.g., fetal cells, present in a sample, e.g., maternal blood and rare cell components, e.g., fetal cell nuclei. The invention further provides a method for preferentially lysing cells of interest in a sample, e.g., to extract clinical information from a cellular component, e.g., a nucleus, of the cells of interest. In general, the method employs differential lysis between the cells of interest and other cells (e.g., other nucleated cells) in the sample.

  • Patent number: 11781187
    Abstract: The present invention provides systems, apparatuses, and methods to detect the presence of fetal cells when mixed with a population of maternal cells in a sample and to test fetal abnormalities, e.g. aneuploidy. The present invention involves labeling regions of genomic DNA in each cell in said mixed sample with different labels wherein each label is specific to each cell and quantifying the labeled regions of genomic DNA from each cell in the mixed sample. More particularly the invention involves quantifying labeled DNA polymorphisms from each cell in the mixed sample.

  • Patent number: 10591391
    Abstract: The present invention provides systems, apparatuses, and methods to detect the presence of fetal cells when mixed with a population of maternal cells in a sample and to test fetal abnormalities, i.e. aneuploidy. In addition, the present invention provides methods to determine when there are insufficient fetal cells for a determination and report a non-informative case. The present invention involves quantifying regions of genomic DNA from a mixed sample. More particularly the invention involves quantifying DNA polymorphisms from the mixed sample.

  • Patent number: 10359429
    Abstract: Method of enriching specific cells from cellular samples are disclosed, comprising contacting in solution a cellular sample with affinity-tagged ligands (ATLs) each comprising a first ligand linked to an affinity tag, wherein the ligand selectively binds a cellular marker of the rare cells and the affinity tag can be selectively captured by a capture moiety, wherein the affinity tags do not comprise a magnetic particle; and flowing the sample through a microfluidic device comprising the capture moiety to selectively retain ATL-bound cells. Methods for enriching circulating tumor cells, and devices for enriching specific cells from cellular samples are also disclosed.
