Abstract: Provided herein are improved methods, compositions, and kits for analysis of nucleic acids. The improved methods, compositions, and kits can enable copy number estimation of a nucleic acid in a sample. Also provided herein are methods, compositions, and kits for determining the linkage of two or more copies of a target nucleic acid in a sample (e.g., whether the two or more copies are on the same chromosome or different chromosomes) or for phasing alleles.

Abstract: Provided herein are methods, compositions, and kits for detecting alleles using a single probe or a single primer set. Also, provided herein are methods, compositions, and kits for detecting allelic variants using a single probe or a single primer set. Also, provided herein are methods, compositions, and kits for determining a polymerization error rate.

Abstract: Provided herein are methods for assessing cancer, comprising analysis of sequence data from a set of cancer-related genes in a tumor sample from a subject, followed by monitoring of a subset of the set in circulating tumor-associated DNA in a fluid sample from the subject. Also provided are kits and systems for practicing any of them methods of the invention.

Abstract: Described herein are methods, systems, compositions and kits to enable determination of a level of degradation of nucleic acids in a sample. For example, the determination of the amount of degradation of RNA in a sample can be accomplished by labeling one or both of the intact 5?- and/or 3?-ends of an mRNA molecule by taking advantage of the unique diol moiety present at these structures. Labeled nucleotides can then be partitioned into droplets and the amount of degradation can be determined by detecting label present in the partitions and making quantitative or qualitative comparisons with a reference sample. In some cases, the degree of degradation is also determined by factoring in the total concentration or quantity of RNA in the sample.

Abstract: The present disclosure provides methods and compositions for performing nucleic acid reactions, such as hot-start digital polymerase chain reaction (dPCR).
