    Abstract: A valve for regulating fluid flow includes a housing base defining a lower cavity and comprising a pinch structure within the lower cavity, a gas inlet providing external access to the lower cavity, a base fluid inlet, and a base fluid outlet. A housing cover defines an upper cavity and comprises a cover fluid inlet and a cover fluid outlet. The cover fluid inlet is in fluidic communication with the base fluid outlet between the upper cavity and the lower cavity, and the cover fluid outlet provides external access from the upper cavity. A diaphragm is disposed between the housing base and the housing cover. A pinch plate is disposed in the lower cavity and comprises a pinch point disposed opposite the pinch structure. A pinch tube is in fluidic communication between the base fluid inlet and the base fluid outlet in the lower cavity.

    Abstract: A method of preparing reagents includes inserting a cartridge into an instrument. The cartridge includes a plurality of reagent enclosures disposed in a cavity of the cartridge and exposing a port to an exterior of the cartridge. Each reagent enclosure includes a reagent container including a reagent and an internal cavity defining a compressible volume, an opening defined through the reagent container to the internal cavity. The method further includes connecting a plurality of fluid ports to the openings of the plurality of reagent enclosures; applying a solution through the fluid ports to at least partially fill the plurality of reagent enclosures; and cycling a pressure of the cavity, whereby for each of the reagent enclosures, during increasing pressure, the solution enters the internal cavity of the reagent container, combines with the reagent, and compresses the compressible volume, and during decreasing pressure, the compressible volume decreases and the reagent is ejected through the opening.

    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. The invention is particularly advantageous in apparatus for performing sensitive multistep reactions, such as pH-based DNA sequencing reactions.

    Abstract: A system for nucleic acid sequencing includes a machine-readable memory and a processor configured to execute machine-readable instructions. The instructions, when executed by the processor, cause the system to expose template polynucleotide strands in a plurality of defined spaces of a sensor array to a series of flows of nucleotide species, the series comprising a sequence of random flows; and obtain, for each of the series of flows of nucleotide species, a signal indicative of how many nucleotide incorporations occurred for that particular flow to determine a predicted sequence of nucleotides corresponding to the template polynucleotide strands.

    Abstract: Mathematical models for the analysis of signal data generated by sequencing of a polynucleotide strand using a pH-based method of detecting nucleotide incorporation(s). In an embodiment, the measured output signal from the reaction confinement region of a reactor array is mathematically modeled. The output signal may be modeled as a linear combination of one or more signal components, including a background signal component. This model is solved to determine the nucleotide incorporation signal. In another embodiment, the incorporation signal from the reaction confinement region of a reactor array is mathematically modeled.

    Abstract: A buffered suspension includes a surfactant and a solid buffer particulate having a point of zero charge at least 1.2 pH units different that the pH of the buffered suspension. The buffered suspension can be prepared by mixing a stock solution with the solid buffer particulate and titrating. A method of preforming a pH sensitive process includes drawing the buffered suspension from a reservoir, filtering the solid buffer particulate from the buffered suspension, and applying the filtered solution to a sensor.
