    摘要： The invention provides methods of conducting a nucleic acid reaction, including methods for performing digital PCR using a "droplet-in-oil" technology. In the methods, the starting sampled is segmented at least partially into a set of sample droplets each containing on average about one or fewer copies of a target nucleic acid. The droplets are passed in a continuous flow of immiscible carrier fluid through a channel that passes through a thermal cycler, whereby the target is amplified. In one implementation, the droplets are about 350 nl each and the number of positively amplified droplets is counted at the near-saturation point.

    摘要： A liquid handling system of a PCR system is instructed to obtain a matrix of samples and reagents for a PCR experiment. A fluid pumping system of the PCR system is instructed to maintain a continuous flow of a transport fluid through a plurality of micro-channels that allows the mixture of the samples and the reagents producing a plurality of mixed sample droplets. One or more post-bridge detection values are received from a post-bridge detection system of the PCR system for each mixed sample droplet to determine if the mixed sample droplet is mixed correctly. A thermocycler of the PCR system is instructed to maintain one or more temperatures for cycling the temperature of the plurality of mixed sample droplets. One or more endpoint detection values are received from an endpoint detection system of the PCR system for each mixed sample droplet to analyze the PCR experiment.

    摘要： The present invention generally relates to devices, systems, and methods for acquiring and/or dispensing a sample without introducing a gas into a microfludic system, such as a liquid bridge system. An exemplary embodiment provides a sampling device including an outer sheath; a plurality of tubes within the sheath, in which at least one of the tubes acquires a sample, and at least one tubes expels a fluid that is immiscible with the sample, in which the at least one tube that acquires the sample is extendable beyond a distal end of the sheath and retractable to within the sheath; and a valve connected to a distal portion of the sheath, in which the valve opens when the tube extends beyond the distal end and closes when the tube retracts to within the sheath.
