  • Publication number: 20190211389
    Abstract: Apparatus and techniques for electrokinetic loading of samples of interest into sub-micron-scale reaction chambers are described. Embodiments include an integrated device and related apparatus for analyzing samples in parallel. The integrated device may include at least one reaction chamber formed through a surface of the integrated device and configured to receive a sample of interest, such as a molecule of nucleic acid. The integrated device may further include electrodes patterned adjacent to the reaction chamber that produce one or more electric fields that assist loading the sample into the reaction chamber. The apparatus may further include a sample reservoir having a fluid seal with the surface of the integrated device and configured to hold a suspension containing the samples.

  • Publication number: 20190211391
    Abstract: The present disclosure provides methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a mixed sample of DNA comprising DNA from both the mother of the fetus and from the fetus, and optionally from genotypic data from the mother and father. The ploidy state is determined by using a joint distribution model to create a plurality of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. The mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias, for example using massively multiplexed targeted PCR.
