Abstract: Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.

Abstract: A method for detecting a tandem duplication in an FLT3 gene of a sample, includes mapping reads corresponding to targeted regions of exons of the FLT3 gene to a reference sequence. A partially mapped read includes a mapped portion, a soft-clipped portion and a breakpoint. Analyzing the partially mapped reads intersecting a column of the pileup includes detecting a duplication in the soft-clipped portion by comparing the soft-clipped portion to the mapped portion adjacent to the breakpoint; determining an insert size of the duplication in the soft-clipped portion; and assigning the partially mapped read to a category based on the insert size. Categories correspond to insert sizes. The categories are filtered and converted into features corresponding to the column. The features corresponding to one or more columns representing a same insert are merged to determine a location and size of a tandem duplication.

Abstract: The invention provides a passive fluidics circuit for directing different fluids to a common volume, such as a reaction chamber or flow cell, without intermixing or cross contamination. The direction and rate of flow through junctions, nodes and passages of the fluidics circuit are controlled by the states of upstream valves (e.g. opened or closed), differential fluid pressures at circuit inlets or upstream reservoirs, flow path resistances, and the like. Free diffusion or leakage of fluids from unselected inlets into the common outlet or other inlets at junctions or nodes is prevented by the flow of the selected inlet fluid, a portion of which sweeps by the inlets of unselected fluids and exits the fluidics circuit by waste ports, thereby creating a barrier against undesired intermixing with the outlet flow through leakage or diffusion.
