    摘要： Microfluidic assemblies, systems, and methods are provided for manipulating fluid samples. Assemblies include an elastically deformable cover layer and a less elastically deformable substrate. The methods include deforming the substrate through the cover layer so that when the cover layer rebounds a new communication results in the assembly between the cover layer and the substrate and/or so that a new barrier wall is formed. Systems for carrying out the methods are also provided.

    摘要： A system is provided for carrying out real time fluorescence-based measurements of nucleic acid amplification products. In a preferred embodiment of the invention, an excitation beam is focused into a reaction mixture through a surface, the reaction mixture containing (i) a first fluorescent indicator capable of generating a first fluorescent signal whose intensity is proportional to the amount of an amplification product in the volume of the reaction mixture illuminated by the excitation beam and (ii) a second fluorescent indicator homogeneously distributed throughout the reaction mixture capable of generating a second fluorescent signal proportional to the volume of reaction mixture illuminated by the excitation beam. Preferably, the excitation beam is focused into the reaction mixture by a lens through a portion of a wall of a closed reaction chamber containing the reaction mixture. The same lens is used to collect the first and second fluorescent signals generated by the first and second fluorescent indicators, respectively, in response to the excitation beam. The ratio of the fluorescent intensities of the first and second fluorescent signals provides a stable quantitative indicator of the amount of amplification product synthesized in the course of the amplification reaction.

    摘要： A multi-channel capillary electrophoresis apparatus is disclosed. The apparatus includes a capillary array assembly comprising a plurality of capillaries, each capillary having a capillary outlet, and an outlet support for supporting the capillary outlets. The apparatus further includes a cuvette defining a receiving slot, a gap region, and a detection zone, where the receiving slot is adapted to removably receive the outlet support, and wherein when the outlet support is inserted into the receiving slot, the capillary outlets are positioned in the gap region in proximity to the detection zone, and a flow channel is formed by the outlet support and the receiving slot such that the flow channel is in fluid communication with the gap region. In addition, the apparatus includes a front plumbing block in fluid communication with the flow channel for supplying a fluid flow through the gap region sufficient to transport material downstream from the capillary outlets to the detection zone.
