    Abstract: 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.

    Abstract: Provided are methods for preparing a library of target nucleic acid sequences, as well as compositions and uses therefor. Methods comprise contacting a nucleic acid sample with a plurality of adaptors capable of amplification of one or more target nucleic acid sequences under conditions wherein the target nucleic acid(s) undergo a first amplification; digesting the resulting first amplification products; repairing the digested target amplicons; and amplifying the repaired products in a second amplification, thereby producing a library of target nucleic acid sequence. Each of the plurality of adaptor compositions comprise a handle and a targeted nucleic acid sequence and optionally one or more tag sequences. Provided methods may be carried out in a single, addition only workflow reaction, allowing for rapid production of highly multiplexed targeted libraries, optionally including unique tag sequences. Resulting library compositions are useful for a variety of applications, including sequencing applications.
