Abstract: Disclosed herein is a simple, sensitive, and fully-recyclable fluorescence resonance energy transfer (FRET)-based multiplex detection platform that overcomes current requirements of complex labeling schemes and complicated data analysis algorithms for employing single-molecule FRET (smFRET) microscopy in multiplexing. While conventional smFRET detection techniques allow for the analysis of one target at a time, the disclosed approach utilizes the gaps between high- and low-FRET signals to provide simultaneous detection and quantification of multiple nucleic acid targets.
Abstract: Provided herein are methods of determining a location of a target analyte in a non-permeabilized biological sample that include the use of a blocking probe.
Abstract: This invention relates generally to compositions and methods for identifying the regulatory network that modulates, controls or otherwise influences T cell balance, for example, Th17 cell differentiation, maintenance and/or function, as well compositions and methods for exploiting the regulatory network that modulates, controls or otherwise influences T cell balance in a variety of therapeutic and/or diagnostic indications. This invention also relates generally to identifying and exploiting target genes and/or target gene products that modulate, control or otherwise influence T cell balance in a variety of therapeutic and/or diagnostic indications.

Abstract: The invention relates to a method for counting cells, such as bacteria and/or somatic cells in liquid samples, such as in dairy products, preferably raw milk. Disclosed is a method comprising a combination of steps that apply dimeric nucleic acid dyes that normally do not penetrate cells (=cell-impermeant dyes), which are rendered cell-permeant by using the right combination of pH, buffer and temperature.

Abstract: Provided are: a method for preparing a DNA unit composition in which the mol number of a plurality of DNA units is more uniform, and a method for creating concatenated DNA. The method for preparing a DNA unit composition has: a step for preparing solutions which contain a plurality of DNA units to which an added sequence is linked, and preparing a solution for each type of DNA unit and a step for, after preparing each of the solutions, measuring the concentration of the DNA unit in each of the solutions in a state where the added sequence is linked to the DNA unit, and on the basis of the results thereof, fractionating each of the solutions and making the mol number of the DNA unit in each of the solutions closer to being identical to one another.
Abstract: The invention generally relates to negative selection of nucleic acids. The invention provides methods and systems that remove unwanted segments of nucleic acid in a sample so that a target gene or region of interest may be analyzed without interference from the unwanted segments. A sample is obtained that includes single-stranded nucleic acid with one or more unwanted segments. Complementary nucleic acid is added to the single-stranded nucleic acid to create a double-stranded region that includes the unwanted segment. The double-stranded region is then digested, leaving single-stranded nucleic acid that includes the target gene or region of interest. This allows paralogs, pseudogenes, repetitive elements, and other segments of the genome that may be similar to the target gene or region of interest to be removed from the sample.
Abstract: The invention relates to a method for modifying a template double stranded polynucleotide, especially for characterisation using nanopore sequencing. The method produces from the template a plurality of modified double stranded polynucleotides. These modified polynucleotides can then be characterised.
Abstract: The present invention addresses the issue of providing a target base sequence detection method, etc., whereby a determination can be readily made regarding whether or not a target base sequence is present in a nucleic acid sample. A fluorescent-labeled detection probe and a competitive probe are added to a nucleic acid sample and caused to hybridize with the nucleic acid in the sample, the fluorescence intensity is measured while changing the temperature of the reaction sample, and first order differentiation is performed on a temperature-fluorescence intensity curve.
Abstract: Automated methods for extracting nucleic acid from one or more tissue samples disposed on slides are disclosed. The methods utilize an automated slide staining apparatus that dispenses a plurality of nucleic acid extraction reagents onto the tissue sample, thus creating an extracted nucleic acid sample. The extracted nucleic acid sample may be used directly in downstream applications such as nucleic acid amplification or sequencing procedures, or may be further purified.
