摘要： Methods and systems for quantification of a target nucleic acid in a sample are provided. The method includes forming a plurality of discrete sample portions. Each of the plurality of discrete sample portions comprising a portion of the sample, and a reaction mixture. The method further includes amplifying the plurality of discrete sample portions to form a plurality of discrete processed sample portions. At least one discrete processed sample portion containing nucleic acid amplification reaction products. Fluorescence signals are detected from the at least one of the plurality of discrete processed sample portions to determine a presence of the at least one target nucleic acid. The method also includes determining the respective volumes of the plurality of the plurality of discrete processed sample portions, and estimating the number of copies-per-unit-volume of the at least one target nucleic acid in the sample. Estimating the number of copies-per-unit-volume is based on the number of discrete processed sample portions determined to contain the at least one target nucleic acid therein.

摘要： A method of aligning a plurality of targets is provided. The method includes generating a plurality of targets. A third phase includes the plurality of targets. The method further includes combining a first phase, a second phase, and the third phase in a volume. The first phase, the second phase, and the third phase are substantially immiscible, and the third phase is in fluid communication with the first phase and the second phase, and the first phase, the second phase, and the third phase are operable to be in a configuration of the third phase between the first phase and the second phase in the volume.
