  • Patent number: 10876151
    Abstract: Ultra-sensitive assays for the detection of mutations, e.g., from blood-based sources of tumor genetic material (circulating tumor cells or plasma), or other settings in which limiting amounts of DNA, e.g., tumor DNA, is available. The assay is exemplified in the estrogen receptor, but is broadly customizable to target mutations in other genes.

  • Publication number: 20200048692
    Abstract: Embodiments of the disclosure encompass methods of enriching one or more target nucleic acid sequences utilizing initial linear amplification steps followed by adaptor ligation to the amplified products. In specific embodiments, the linear amplification employs primer extension that spans the target nucleic acid sequences and occurs at least in two or more cycles following which adaptors with unique identifier sequences are attached to the extension products.

  • Publication number: 20170029813
    Abstract: The present invention generally relates to microfluidic devices, including methods and systems for tagging droplets within such devices. In some aspects, microfiuidic droplets are manipulated by exposing the droplets (or other discrete entities) to a variety of different conditions. By incorporating into the droplets a plurality of nucleic acid “tags,” and optionally amplifying the nucleic acids, e.g., within the droplets, the conditions that a droplet was exposed to may be encoded by the nucleic acids. Thus, even if droplets exposed to different conditions are mixed together, the conditions that each droplet encountered may still be determined, for example, by sequencing the nucleic acids.
