摘要:
The present invention provides novel microfluidic devices and methods that are useful for performing high-throughput screening assays and combinatorial chemistry. The invention provides for aqueous based emulsions containing uniquely labeled cells, enzymes, nucleic acids, etc., wherein the emulsions further comprise primers, labels, probes, and other reactants. An oil based carrier-fluid envelopes the emulsion library on a microfluidic device, such that a continuous channel provides for flow of the immiscible fluids, to accomplish pooling, coalescing, mixing, sorting, detection, etc., of the emulsion library.

摘要:
A microfluidic device is described that has a slug mixing arrangement. A reaction well has an input flow channel with a first valve near the reaction well, and a second valve further from the reaction well. A fluid source is connected to the segment in between the two valves. A second fluid source is connected behind the second valve. The channel between the two valves receives the first fluid by blind filling when the two valves are closed. The reaction well receives the first fluid followed by the second fluid when the first and second valves are open.

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.
