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: Methods of making a droplet-generating device. In an exemplary method, an upper member is injection molded. The upper member includes a bottom surface and also includes a first microfluidic channel, a second microfluidic channel, and a third microfluidic channel each formed in the bottom surface. The upper member has a plurality of openings each extending completely through the upper member from the bottom surface and creating a side wall region of a sample well, a carrier well, and a droplet well. A cover layer is attached to the bottom surface of the upper member, such that the cover layer seals a bottom side of each microfluidic channel. The microfluidic channels meet one another to create a droplet-generation region. The sample well, the carrier well, and the droplet well are connected to the droplet-generation region via the first, second, and third microfluidic channels, respectively.

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.

An exemplary device comprises a substantially planar base portion including a bottom surface having a plurality of microfluidic channels formed therein as recessed regions of the bottom surface. The device also comprises a plurality of protrusions projecting from a top surface of the base portion and each formed integrally with the base portion. The device further comprises a sample well, a carrier well, and a droplet well. Each well has an upper portion created by one of the protrusions. A cover layer is attached to the bottom surface of the base portion and seals a bottom side of each microfluidic channel.

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: 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.
