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:
The present invention provides methods, compositions, kits, systems and apparatus that are useful for multiplex PCR of one or more nucleic acids present in a sample. In particular, various target-specific primers are provided that allow for the selective amplification of one or more target sequences. In one aspect, the invention relates to target-specific primers useful for the selective amplification of one or more target sequences associated with cancer or inherited disease. In some aspects, amplified target sequences obtained using the disclosed methods, kits, systems and apparatuses can be used in various downstream processes including nucleic acid sequencing and used to detect the presence of genetic variants.

In particular, the methods generally relate to normalizing the concentration of target nucleic acid molecules from a sample. In one aspect, the invention relates to purifying a primer extension product from a primer extension reaction mixture. In some aspects, nucleic acid molecules obtained using the disclosed methods, kits, systems and apparatuses can be used in various downstream processes including nucleic acid sequencing.
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.

Abstract:
Methods, compositions and kits are described for resequencing, confirming or verifying Next Generation Sequencing (NGS) results with Sanger Sequencing. These methods are particularly useful for samples having very limited quantities such as formalin-fixed, paraffin-embedded (FFPE), Laser Capture Microdissection (LCM), fine needle biopsies or aspirates.
