Microfluidic chip, device and system for the generation of aqueous droplets in emulsion oil for nucleic acid amplification

Disclosed is a process for clonal pre-amplification of a nucleic acid involving the steps of (i) providing a plurality of different nucleic acid molecules (b) attaching adaptor sequences to the 3' ends and 5&#x2032; ends of the nucleic acid molecules (c) preparing a water in oil emulsion wherein the majority of water droplets comprises one or none member of the plurality of different nucleic acid molecules (d) clonally amplifying the plurality of different nucleic acid molecules. In particular, the different nucleic acid molecules are mRNA molecules.

Clonal pre-amplification in emulsion

The present invention relates to a method of specifically releasing a one or more members of a sub-group of objects from an entity, a method of detecting a subject's disease by detecting one or more members of a sub-group of biological entities indicative of the disease and a method of isolating one or more members of a sub-group of objects from a group of objects.

Methods of specifically releasing a sub-group of objects

The present invention provides a solid support which is preferably a bead comprising at least two sequence specific amplification primers wherein at least one primer is bound to the support with an inducible cleavable linker. The present invention also provides various method for preparing a solid support comprising at least two sequence specific primers, further characterized in that at least one of the primers is cleavable.

Solid support for high-throughput nucleic acid analysis

The present invention is directed to method for analyzing multiple nucleic acid molecules of interest comprising in the steps of (i) providing a plurality of beads, characterized in that each bead comprises at least two sequence specific amplification primers, further characterized in that at least one of the primers is bound to the bead via a cleavable linker, (ii) capturing the nucleic acid molecules of interest from a sample, (iii) clonally isolating the plurality of beads, (iv) cleaving the at least one primer, (v) clonally amplifying the nucleic acid thereby creating multiple amplification products, and (vi) analyzing the amplification products.

Miniaturized, high-throughput nucleic acid analysis

An integrated instrument for oligonucleotide synthesis and PCR, and a system and method thereof are disclosed. The integrated instrument is basically composed of two independent modules. The first module is a unit for chemical de novo synthesis of oligonucleotides such as oligonucleotide primers and/or oligonucleotide hybridization probes. The second module is a unit for performing an analytical polymerase chain reaction amplification in real time, i.e. a qPCR. The two modules are operatively linked to each other in such a way that a user can load a nucleic sample to be analyzed into the integrated instrument and perform a PCR reaction by programming the instrument without a previous external synthesis of oligonucleotide amplification primers.

Integrated instrument performing synthesis and amplification, and a system and method thereof

The current invention restates substituted nitroindole nucleosides as both terminal as well as internal building blocks of labeled oligonucleotide probes for the detection, analysis and quantitation of nucleic acids. The substituent comprises a linker and a detectable group or a linker and a reactive group for post synthesis coupling. These modified nucleosides grant access to a wide application area. These new substituted nitroindole nucleosides can be used as labeling reagents for the facile preparation of, e.g., optimized hybridization probes, simple probes, TAQMAN-probes or molecular beacon probes.
