Abstract: Methods of partition-based analysis. In an exemplary method, a device having a port fluidically connected to a chamber may be selected. A sample-containing fluid may be placed into the port. The sample-containing fluid may be moved from the port to the chamber. Partitions of the sample-containing fluid may be formed. A monolayer of the partitions in the chamber may be created. At least a portion of the monolayer may be imaged.

Abstract: Method of haplotype analysis. In an exemplary method, an aqueous phase containing nucleic acid may be partitioned into a plurality of discrete volumes. At least one allele sequence may be amplified in the volumes from each of a first polymorphic locus and a second polymorphic locus that exhibit sequence variation in the nucleic acid. At least one measure of co-amplification of allele sequences from both loci in the same volumes may be determined. A haplotype of the first and second loci may be selected based on the at least one measure of co-amplification.

Abstract: A system, including method and apparatus, for generating droplets suitable for droplet-based assays. The disclosed systems may include either one-piece or multi-piece droplet generation components configured to form sample-containing droplets by merging aqueous, sample-containing fluid with a background emulsion fluid such as oil, to form an emulsion of sample-containing droplets suspended in the background fluid. In some cases, the disclosed systems may include channels or other suitable mechanisms configured to transport the sample-containing droplets to an outlet region, so that subsequent assay steps may be performed.

Abstract: System, including methods, apparatus, and kits, for forming emulsions. In an exemplary method of generating droplets, a device may be selected that includes a plurality of emulsion-formation units each including a sample well, a continuous-phase well, a droplet well, and a channel network that fluidically interconnects the wells and creates a droplet-generation region. A discrete volume of sample-containing fluid may be placed into the sample well of each emulsion-formation unit, and a discrete volume of continuous-phase fluid into the continuous-phase well of each emulsion-formation unit. Pressure may be applied to the device with a fluidics assembly after the step of placing, such that the plurality of emulsion-formation units generate droplets in parallel with one another. A pressure signal may be detected from the fluidics assembly. Application of the pressure may be stopped when the pressure signal indicates that a sample well is empty.

Abstract: System, including methods, apparatus, and kits, for forming and concentrating emulsions. An exemplary system may comprise a device including a sample well configured to receive sample-containing fluid, a continuous-phase well configured to receive continuous-phase fluid, a droplet well, and a channel network interconnecting the wells. The system also may comprise an instrument configured to operatively receive the device and to create (i) a first pressure differential to produce an emulsion collected in the droplet well and (ii) a second pressure differential to decrease a volume fraction of continuous-phase fluid in the emulsion, after the emulsion has been collected in the droplet well, by selectively driving continuous-phase fluid, relative to sample-containing droplets, from the droplet well.

Abstract: Method of analysis. In the method, a microfluidic device defining a flow path extending from an inlet to an outlet may be selected. A sample-containing fluid may be introduced into the flow path via the inlet. Volumes of the sample-containing fluid may be isolated from one another on the flow path. A two-dimensional monolayer of the volumes may be imaged. The two-dimensional monolayer may be formed along the flow path between the inlet and the outlet.
