Abstract:
The present invention relates to a method for enriching an infectious agent in an acellular fraction of a biological fluid using detergents and nucleic acids-digesting enzymes. The present invention also relates to a method for modulating the accessibility of host nucleic acids (HNA) in an acellular fraction of a biological fluid using detergents and nucleic acids-digesting enzymes, and to a method for detecting infectious agents in an acellular fraction from a biological fluid.

Abstract:
The present invention relates to a method for the highly specific, targeted capture of regions of human genomes and transcriptomes from the blood, i.e. from cell free circulating DNA, exosomes, microRNA, circulating tumor cells, or total blood cells, to allow for the highly sensitive detection of mutation, expression, copy number, translocation, alternative splicing, and methylation changes using combined nuclease, ligation, polymerase, and massively parallel sequencing reactions. The method generates a collection of different circular chimeric single- stranded nucleic acid constructs, suitable for sequencing on multiple platforms. In some embodiments, each construct of the collection comprised a first single stranded segment of original genomic DNA from a host organism and a second single stranded synthetic nucleic acid segment that is linked to the first single stranded segment and comprises a nucleotide sequence that is exogenous to the host organism. These chimeric constructs are suitable for identifying and enumerating mutations, copy changes, translocations, and methylation changes. In other embodiments, input mRNA, IncRNA, or miRNA is used to generate circular DNA products that reflect the presence and copy number of specific mRNA's, IncRNA's splice-site variants, translocations, and miRNA.
Abstract:
A method of analysing for a single stranded nucleic acid present, or potentially present, in a sample comprises a step in which the target nucleic acid (if present in the sample) displaces – and hybridises to – a reporter strand originally present in an interrogating duplex structure comprised of the reporter strand and a displaceable shorter strand. The reporter strand is tagged at or adjacent one end thereof with a reporter moiety capable of providing a detectable signal. The reporter/target duplex structure is such that the reporter strand may be selectively enzymatically digested (e.g. by means of λ- exonuclease) from its end opposite the reporter moiety to release that moiety for direct or indirect detection and regenerate single stranded target, which may then cycle through a plurality of the displacement and digestion steps to result in amplification of signal.
Abstract:
Disclosed herein are compositions and methods for the processing, amplification and detection of polynucleotides using target-specific oligonucleotides (TSOs). Hybridization of TSOs to target polynucleotides guides target processing into and purification of small target fragments that then can be amplified and detected with high sensitivity and reproducibility. The method is specifically beneficial for highly degraded polynucleotides found in biological samples.
Abstract:
The present invention relates to the detection of a target nucleic acid sequence from a DNA or a mixture of nucleic acids by a PCE-hCTO (PTO Cleavage and Extension using hCTO) assay on a solid phase. According to the present invention, the extended duplex is formed in a liquid phase in a target-dependent manner and then its presence is detected on a solid phase. Since hCTO is not immobilized onto a solid phase, the extended duplex is more effectively formed in a liquid phase.
