The present invention provides novel primers and methods for the detection of specific nucleic acid sequences. The primers and methods of the invention are useful in a wide variety of molecular biology applications and are particularly useful in allele specific PCR.

Methods of detecting affinity interactions between at least two molecules of interest are provided. The method comprises: a. forming a plurality of interactors by coupling each molecule of interest with at least one nucleic acid moiety comprising an identification sequence element and at an association element; b. promoting an association between at least two nucleic acid moieties from different interactors to form a plurality of unique associated oligonucleotides, wherein each nucleic acid moiety may form more than one unique associated oligonucleotide, and wherein each unique associated oligonucleotide comprises at least two identification sequence elements derived from the at least two nucleic acid moieties; c. selecting the plurality of unique associated oligonucleotides; and d. subjecting the selected associated oligonucleotides to an analysis that permits detection of the at least two identification sequence elements. Similar methods directed to detecting functional interactions, libraries of interactors employable in the present methods, and kits comprising those libraries are also provided.

The present invention relates in one aspect to a method for analysing the frequency of interaction of a target nucleotide sequence with one or more nucleotide sequences of interest (eg. one or more genomic loci) comprising the steps of: (a) providing a sample of cross-linked DNA; (b) digesting the cross-linked DNA with a primary restriction enzyme; (c) ligating the cross-linked nucleotide sequences; (d) reversing the cross linking; (e) optionally digesting the nucleotide sequences with a secondary restriction enzyme; (f) optionally ligating one or more DNA sequences of known nucleotide composition to the available secondary restriction enzyme digestion site(s) that flank the one or more nucleotide sequences of interest; (g) amplifying the one or more nucleotide sequences of interest using at least two oligonucleotide primers, wherein each primer hybridises to the DNA sequences that flank the nucleotide sequences of interest; (h) hybridising the amplified sequence(s) to an array; and (i) determining the frequency of interaction between the DNA sequences.

The present invention discloses disease-linked SNPs, microRNAs, and microRNA-targeted mRNAs relevant to the pathogenesis of several major human disorders including, but not limited to, multiple types of cancers, type 2 diabetes, type 1 diabetes, Crohn's disease, coronary artery disease, hypertension, rheumatoid arthritis, bipolar disorder. Also provided are methods for the identification of disease phenotype-defining sets of SNPs, microRNAs, and mRNAs that are defined here as a “consensus disease phenocode” as well as methods of using the information provided by these consensus disease phenocodes for various diagnostic, prognostic, and/or therapeutic applications.

This invention relates to the field of detection of polycyclic aromatic hydrocarbons in food. The invention discloses a hydrophobic porous organic polymer solid-phase extraction material and the application of the same to the analysis of the persistent pollutant polycyclic aromatic hydrocarbons in food. The material is rich in hydrophobic benzene ring functional groups and mesoporous and microporous structures, has a large specific surface area, improves the enrichment efficiency of sample pretreatment in analysis and detection of polycyclic aromatic hydrocarbons in food and reduces matrix interference in detection of a target object. Compared with traditional solid-phase extraction materials, the material of the invention has the following advantages: the material has good physical and chemical stability; the functional groups are embedded in the skeleton of the material, and are high in content, stable and not prone to loss; and the material has long service life and can be repeatedly used.

The invention provides a micro-fluidic chip for detecting glycosylated hemoglobin and a detection method thereof. The micro-fluidic chip is sequentially provided with a cover plate layer, a fluid layer with a hollow channel structure and a substrate layer from top to bottom, and the hollow channel structure and the substrate layer jointly form a sample detection unit. A sample injection through hole and a waste liquid leading-out through hole are respectively formed in the cover plate layer. The sample detection unit comprises one or more sample injection chambers, a dilution chamber, an affinity chromatography channel, a detection chamber and a waste liquid pool. The sample injection through hole is communicated with the sample injection chamber, and the waste liquid leading-out through hole is communicated with the waste liquid pool. Sample introduction, sample dilution and optical and electrical detection are integrated through the micro-fluidic chip; the operation process is greatly simplified, the consumption of samples and reagents is reduced, expensive equipment is not needed, the use cost is largely reduced, the on-site instant detection of glycosylated hemoglobin can be realized, and huge economic value and social value are created.
