  • Publication number: 20220333209
    Abstract: Disclosed herein are systems and methods for localization of a disease state (e.g., tissue of origin of cancer) using nucleic acid samples. In an embodiment, a method comprises receiving a plurality of cancer signals of a sample, each cancer signal indicating a probability that the sample is associated with a different disease state of a plurality of disease states. The method determines a first cancer signal having a greatest probability among the plurality of cancer signals. In accordance with a determination that the first cancer signal satisfies a criterion, the method associates the sample with a first disease state. In accordance with a determination that the first cancer signal does not satisfy the criterion, the method determines a second cancer signal having a second greatest probability among the plurality of cancer signals, and associates the sample with the first disease state and a second disease state.

  • Publication number: 20220184622
    Abstract: In accordance with embodiments herein a method for capturing cells of interest in a digital microfluidic system is provided, comprising utilizing a droplet actuator to transport a sample droplet to a microwell device. The microwell device includes a substrate having a plurality of microwells that open onto a droplet operations surface of the microwell device. The sample droplet includes cells of interest that enter the microwells. The method introduces capture beads to the microwells, and the capture elements are immobilized on the capture beads. The method utilizes the droplet actuator to transport a cell lysis reagent droplet to the microwell device. Portions of the cell lysis reagent droplet enter the microwells and, during an incubation period, cause the cells of interest to release analyte that is captured by the capture elements on the capture beads.
