Abstract: Present disclosure provides a method including isolating DNA from a source, thereby providing a composition including the isolated DNA. The isolated DNA has at least first and second target regions, where the length of the second target region is greater than the length of the first target region. The method further includes quantifying a total mass of the isolated DNA, quantifying a first quantification cycle (Cq) of the first target region and a second Cq of the second target region, and calculating a Q-ratio for the isolated DNA by dividing the second Cq by the first Cq. The method further includes determining a value for a quality-mass constant (kQm), estimating a required input mass by dividing kQm by the Q-ratio, and preparing the isolated DNA for sequencing if the total mass of the isolated DNA in the composition is equal or greater than the required input mass.

Abstract: Disclosed are methods and compositions for detecting structural rearrangements in a genome using rearrangement-specific enrichment probes or rearrangement- specific amplification primers.

Abstract: The invention is a novel adaptor containing barcodes for sequencing nucleic acids with a reduced rate of errors.

Abstract: The present disclosure provides a kit for preparing a library of nucleic acids. The kit includes first and second oligonucleotide, each having a tail sequence, a common sequence, and at least one of a unique identifier sequence, and a variable length punctuation mark. The kit further includes a first primer having a first sample identifier sequence and a first priming sequence at a 3? end of the first primer. The first priming sequence includes the tail sequence of the first oligonucleotide. The kit further includes a second primer having a second sample identifier sequence and a second priming sequence at a 3? end of the second primer. The second priming sequence is complimentary to the second tail sequence of the second oligonucleotide.

Abstract: Techniques for cancer patient management, and more particularly, to techniques for ultrasensitive detection of circulating nucleic acid with prior knowledge of variants to be monitored in the blood. An exemplary technique includes detecting one or more variants in a sample of cell free DNA from a subject. The one or more variants are selected from a plurality of variants known to be specific to a tumor or disease area of the subject. The technique further includes counting the detected one or more variants, determining a tumor burden based on the count of the one or more variants, and determining a statistical significance of the tumor burden based on whether the detection of the one or more variants is associate with true signals or background noise.
