    摘要: System, including methods, apparatus, compositions, and kits, for making and using a stabilized emulsion. A method of generating a stabilized emulsion is provided. In the method, an aqueous phase may be provided. The aqueous phase may include an effective concentration of one or more skin-forming proteins. An emulsion may be formed. The emulsion may include droplets of a dispersed phase disposed in a continuous phase, with the aqueous phase being the continuous phase or the dispersed phase. The emulsion may be heated to create an interfacial skin between each droplet and the continuous phase, to transform the droplets into capsules.

    摘要: System, including methods and compositions, for making and using emulsions that include a silicone oil and a silicone surfactant. The emulsions may include aqueous droplets disposed in a continuous phase that includes a silicone oil and a silicone surfactant. The aqueous droplets may contain an analyte, optionally at partial occupancy, and/or a luminescent (e.g., photoluminescent) reporter. An assay of the analyte may be performed with the droplets. In some cases, signals may be detected from the droplets, and a characteristic of the analyte, such as an analyte level or activity, may be determined based on the signals.

    摘要: Method of detecting a signal from droplets for instrument calibration. In the method, a calibration standard for a droplet detection instrument may be received. The calibration standard may have been shipped at least one kilometer when received. The calibration standard may include a mixture of first droplets and second droplets. Each of the first and second droplets may be encapsulated by an immiscible carrier liquid and may have a stabilizing droplet skin that is formed by heating and that includes a skin-forming protein. Each the first droplets may contain a fluorescent dye, and each of the second droplets may contain a fluorescent dye. A fluorescence signal may be detected from a plurality of the first and second droplets with a droplet detection instrument. The fluorescence signal may be stronger for the first droplets than the second droplets.

    摘要: This disclosure provides systems, devices, and methods for sample preparation and/or analysis comprising a droplet generator having a first channel in fluid communication with a carrier fluid reservoir and a second channel in fluid communication with a sample reservoir. The first channel and second channel may meet at an intersection that receives a sample from the sample reservoir and a carrier fluid from the carrier fluid reservoir and generates one or more droplets that flow along a droplet channel to a droplet reservoir. An energy application member in thermal communication with the intersection, at least a portion of the droplet channel, the sample reservoir and/or the carrier fluid reservoir may provide energy to an individual droplet of the one or more droplets, such as at the intersection and/or as the droplet moves along the droplet channel to the droplet reservoir.
