Contemplated methods and devices are drawn to preparation and analysis of analytes from biological samples. In a preferred embodiment the analytes are nucleic acids that are both released from biological compartments present in the sample and fragmented through the use of a voltage potential applied to a pair of electrodes. The nucleic acids thus prepared are subsequently characterized.

Diagnostic and sample preparation devices and methods

Contemplated methods and devices are drawn to preparation and analysis of analytes from biological samples. In a preferred embodiment the analytes are nucleic acids that are both released from biological compartment present in the sample and fragmented through the use of a voltage potential applied to a pair of electrodes. The nucleic acids thus prepared are subsequently characterized.

The methods and compositions of the present invention allow for the evaluation of a nucleotide expansion, contraction or deletion. In one embodiment, the present invention provides a method for detecting a nucleotide expansion, contraction or deletion comprising amplifying a target nucleic acid sequence with a primer pair, each primer comprising a target specific sequence and a differentiating tag sequence, labeling the target nucleic acid sequence to produce a dual-tagged amplification product; digesting the dual-tagged amplification product to produce an expansion region fragment and an internal control fragment; hybridizing the fragments to separate capture complexes; detecting the signals produced by the labels on the immobilized fragments and comparing the intensity of the signals to detect the nucleotide expansion, contraction or deletion region.

Use of dual-tags for the evaluation of genomic variable repeat regions

A unimolecular probe for hybridization to a molecule comprising a target nucleic acid sequence, the probe includes: a first nucleic acid sequence complementary to the target sequence (target-binding sequence); and a second nucleic acid sequence complementary to a portion of the first nucleic acid sequence and capable of hybridization therewith to form a first intramolecular duplex. In use, the target and target-bind sequence hybridize to form a duplex. A probe can be used to detect a molecule containing the target sequence, act as a primer for synthesis or amplification, etc.

Capture moieties for nucleic acids and uses thereof

The present invention provides a method for the simultaneous identification of two or more single base changes in a plurality of target nucleotide sequences that are markers associated with cardiovascular diseases such as deep vein thrombosis and the like. Multiplex detection is accomplished using multiplexed tagged allele specific primer extension (ASPE) and hybridization of such extended primers to a probe, preferably an addressable anti-tagged support.

Method of detecting mutations associated with thrombosis

A unimolecular probe for hybridization to a molecule comprising a target nucleic acid sequence, the probe includes: a first nucleic acid sequence complementary to the target sequence (target-binding sequence); a second nucleic acid sequence complementary to a portion of the first nucleic acid sequence and capable of hybridization therewith to form a first intramolecular duplex. In use, the target and target-binding sequence hybridize to form a duplex. A probe can be used to detect a molecule containing the target sequence, act as a primer for synthesis or amplification, etc.
