Abstract: The invention is directed to compositions and methods for rapidly detecting, amplifying, and quantitating one or more pathogen-specific nucleic acids in a biological sample, and in particular, samples obtained from patients with sepsis. The invention also provides diagnostic kits containing specific amplification primers, and labeled detection probes that specifically bind to the amplification products obtained therefrom. The invention is also directed to detecting the quantity or ratio of genomic sequences and mRNA sequences of an individual suspected of being infected with an infectious agent over time to assess the progress of the infection over time. Also disclosed are compositions and methods for the isolation and characterization of nucleic acids that are specific to one or more pathogens, such as, for example, Influenza virus, Mycobacterium tuberculosis, Plasmodium, and/or HIV from a wide variety of samples including those of biological, environmental, clinical and/or veterinary origin.

Abstract: The invention provides a method for identifying or detecting small RNA (sRNA) predictors of a disease or a condition. The method comprises identifying one or more sRNA sequences that are present in one or more samples of an experimental cohort, and which are not present across a comparator cohort; and optionally identifying one or more sRNA sequences that are present in one or more samples of a comparator cohort, and which are not present across an experimental cohort. In contrast to identifying dysregulated non-coding RNAs (such as miRs that are up- or down-regulated), the invention identifies sRNAs that are binary predictors, that is, present in one cohort (e.g., an experimental cohort) and not another (e.g., a comparator cohort). Further, by quantifying reads for individual sequences (e.g., iso-miRs), without consolidating reads to annotated reference sequences, the invention unlocks the diagnostic utility of miRs and other sRNAs.

Abstract: The present invention provides biomarkers for the diagnosis and prognosis of endometriosis. Generally, the methods of this invention find use in diagnosing or for providing a prognosis for endometriosis by detecting the expression levels of biomarkers, which are differentially expressed (up- or down-regulated) in endometrial cells from a patient with endometriosis. Similarly, these markers can be used to diagnose reduced fertility in a patient with endometriosis or to provide a prognosis for a fertility trial in a patient suffering from endometriosis. The present invention also provides methods of identifying a compound for treating or preventing endometriosis. Finally, the present invention provides kits for the diagnosis or prognosis of endometriosis.

Abstract: Disclosed are methods for amplifying a nucleic acid target region using an amplification oligomer comprising a target-binding segment and a heterologous displacer tag situated 5? to the target-binding segment. Initiation of an amplification reaction from the tagged amplification oligomer produces an amplicon comprising the displacer tag, such that once the complement of the displacer tag has been incorporated into a second amplicon, a displacer oligonucleotide having a sequence substantially corresponding to the displacer tag sequence is used to participate in subsequent rounds of amplification for displacement of an extension product primed from a site within the second amplicon 5? to the displacer priming site. Also disclosed are related kits and reaction mixtures comprising the displacer-tagged amplification oligomer and corresponding displacer oligonucleotide.

The complementary sequence of the 1?-th sequence is a loop primer sequence. The primer set contains a first elongation primer containing a first elongation primer sequence and a complementary sequence of the sixth sequence, and a second elongation primer containing a second elongation primer sequence, the fourth, the third, and the second sequence.
Abstract: High-fidelity, high-throughput nucleic acid sequencing enables healthcare practitioners and patients to gain insight into genetic variants and potential health risks. However, previous methods of nucleic acid sequencing often introduces sequencing errors (for example, mutations that arise during the preparation of a nucleic acid library, during amplification, or sequencing). Provided herein are methods and compositions for sequencing nucleic acids. Further provided are methods of identifying an error in a nucleic acid sequence.
Abstract: Methods and materials are disclosed for use in recovering a biopolymer from a solution. In particular, the invention provides methods for extraction and isolation of nucleic acids from biological materials. The nucleic acids can be separated by forming a stable complex with soluble polysaccharide polymers and magnetic particles, in the presence of detergents and solvent. When the particles are magnetically separated out of the solution, the nucleic acids are separated with them. The nucleic acids can subsequently be released and separated from the particles. The nucleic acid preparation is useful for achieving efficient and accurate results in downstream molecular techniques such as quantification, identification of the source of the nucleic acids, and genotyping.
