Abstract: Methods of double-stranded nucleic acid sequence determination and assembly that are able to identify insertions, deletions, repeat region sizes and genomic rearrangements, for example, are disclosed herein, which can use relatively large labeled nucleic acid fragments to analyze the structure of even larger genetic regions. In some embodiments these methods involve the use of certain parameters which unexpectedly improve overall method performance. In some embodiments these methods involve sample labeling that does not result in the formation of single-stranded nucleic acid fragment labeling intermediaries.

Abstract: Systems are provided for detecting and quantitating short nucleic acid molecules.

Abstract: Methods are provided for detecting and quantitating molecules using fluidics. In preferred embodiments, the methods comprise analyzing blood to detect the presence of circulating DNA or cells from a fetus or tumor.

Abstract: Methods of labeling DNA molecules comprising the use of one or more dCas proteins and one or more labeled guide RNAs (gRNAs) are described herein. In some embodiments, the labeled DNA molecules are elongated in fluidic nanochannels, where they can be analyzed.

Abstract: Methods are provided for characterizing a sample comprising polynucleotide sequences. The methods can comprise labeling nucleic acid molecules of the sample, translocating the plurality of labeled sample nucleic acid molecules though one or more fluidic nanochannels, detecting physical counts of signals from the labeled sample nucleic acid molecule, and determining a copy number of a genome or a fragment or fragments thereof in the sample.

Abstract: Methods and compositions for processing polynucleotides are provided according to some embodiments herein. In some embodiments, a sample is immobilized in a porous matrix, and non-polynucleotides are removed from the sample. In some embodiments, polynucleotides are labeled or enzymatically modified the matrix. In some embodiments, labeled or enzymatically modified polynucleotides are removed from the matrix for analysis.

Abstract: According to some embodiments herein, methods and kits for labeling and analyzing nucleic acids are provided. In some embodiments, sequence-specific labeling is performed on polynucleotide sequences associated with a host genome, and the presence or absence of patterns characteristic of extragenomic sequences are determined.

Abstract: Provided are compositions and methods for identifying pairs of interacting proteins. The pair of plasmids is adapted for use in a modified two hybrid system wherein each plasmid comprises a recombinase recognition site. The method comprises the steps of providing cDNAs encoding test polypeptides, inserting the cDNAs into the first and second plasmids, recombining the first and second plasmids to obtain recombined plasmids, isolating and digesting the recombined plasmids to obtain cDNAs encoding pairs of interacting proteins, and determining the sequence of the digested fragments to determine pairs of interacting proteins.
