  • Publication number: 20200399677
    Abstract: Methods for differentially quantifying nucleic acids in a biological sample using differentially methylated loci include forming a digested biological sample in a solution of a methylation-sensitive restriction enzyme to cleave an unmethylated group of nucleic acids, forming a reaction mixture, amplifying the reaction mixture to generate a first signal from the a group of detection probes and a second signal from a second group of detection probes, determining a ratio comprising a first value derived from the first signal to a second value derived from the second signal, and identifying the proportion of nucleic acid in the biological sample originating from the first plurality of nucleic acids.

  • Patent number: 10536352
    Abstract: In one embodiment, a method includes extracting a cross-platform data-collection schema based, at least in part, on information available via heterogeneous interfaces of a plurality of source platforms. The cross-platform data-collection schema identifies a plurality of collectable data points in relation to particular source platforms. The method further includes configuring a cross-platform data-collection schedule for the plurality of source platforms. The cross-platform data-collection schedule indicates a collected subset of the plurality of collectable data points in relation to collection frequencies. The method also includes causing data values for the collected subset to be collected on an ongoing basis as dictated by the cross-platform data-collection schedule. Furthermore, the method includes processing a proposed change to at least one of the collected subset and the collection frequencies.
