Abstract: The invention provides methods and apparatus for carrying out multiple amplification reactions in a single reaction chamber by successive cycles of loading reaction mixture, amplifying, and removing spent reaction mixture in a fluidly closed reaction system. In particular, the present invention allows amplification of a plurality of target polynucleotides from a single sample by carrying out under closed-loop control successive amplifications of different target polynucleotides from different portions of the sample.

Abstract: A fluid control and processing system for controlling fluid flow among a plurality of chambers comprises a body including a fluid processing region continuously coupled fluidicly with a fluid displacement region. The fluid displacement region is depressurizable to draw fluid into the fluid displacement region and pressurizable to expel fluid from the fluid displacement region. The body includes at least one external port. The fluid processing region is fluidicly coupled with the at least one external port. The fluid displacement region is fluidicly coupled with at least one external port of the body. The body is adjustable with respect to the plurality of chambers to place the at least one external port selectively in fluidic communication with the plurality of chambers.
Abstract: A lid apparatus for a multi-chambered container. The lid apparatus has a top-lid that is hingedly attached to a bottom-cap. The top-lid includes one or more openings for fluid filling multiple passages that extend from the bottom-cap. A lower bottom-cap includes welding features for welding to the multi-chambered container.
Abstract: An apparatus for disrupting cells or viruses comprises a container having a chamber for holding the cells or viruses. The container includes at least one flexible wall defining the chamber. The apparatus also includes a transducer for impacting an external surface of the flexible wall to generate pressure waves in the chamber. The apparatus also includes a pressure source for increasing the pressure in the chamber. The pressurization of the chamber ensures effective coupling between the transducer and the flexible wall. The apparatus may also include beads in the chamber for rupturing the cells or viruses.

Abstract: The invention is directed to systems, methods, and apparatus for carrying out multi-stage amplification reactions, especially under fluidly closed conditions. In one aspect, methods of the invention are carried out in a fluidly closed reaction system that permits the isolation of a portion of a first (or prior) reaction mixture and its use as a sample or specimen in a second (or subsequent) reaction mixture, thereby substantially avoiding interfering effects that first reaction components may have in the second reaction if both reaction mixtures were simply combined together. In this aspect, systems, methods, and apparatus of the invention may be used with any amplification reaction that permits multiple stages of amplification based on the use of nested primers.

Abstract: A cartridge for conducting a chemical reaction includes a body having at least one flow path formed therein. The cartridge also includes a reaction vessel extending from the body for holding a reaction mixture for chemical reaction and optical detection. The vessel comprises a rigid frame defining the side walls of a reaction chamber. The frame includes at least one channel connecting the flow path to the chamber. The vessel also includes flexible films or sheets attached to opposite sides of the rigid frame to form opposing major walls of the chamber. In addition, at least two of the side walls are optically transmissive and angularly offset from each to permit real-time optical detection of analyte in the reaction chamber.
