Abstract:
A device for performing biological sample reactions comprising a plurality of flow cells each with at least one port for receiving reaction fluids delivered to a chamber of each flow cell and a manifold configured to receive the plurality of flow cells, wherein the manifold is configured to receive at least one reaction fluid, and wherein each flow cell is configured with a sample holder wherein the sample holder contains biological sample.
Abstract:
Devices, assemblies, systems and methods described herein enable detection of as few as a single copy of a target nucleic acid molecule. Polynucleotides copied from a single or a small number of target nucleotide(s) within regions near to an initial copying site may be detected by optical or other methods as disclosed herein. Devices, assemblies and systems may comprise probes and/or primer molecules. Systems comprising optical assemblies, thermal assemblies and reaction assemblies (having reaction chambers for amplification of target nucleic acid molecules) are provided in which used reaction assemblies may be replaced to provide reusable devices. Systems comprising analytical assemblies and detection assemblies are provided in which an assay cartridge having assay chambers may engage a thermal assembly for amplification of target nucleic acid molecules. These devices, systems and methods offer the advantages of detection of as few as a single copy of a target nucleic acid molecule.
Abstract:
A system and method are provided for large volume sample amplification adaptable for use with conventional PCR-based reactions as well as emulsion-based PCR reactions. A sample is retained in a pouch or flexible bag which permits bulk PCR amplification with efficient heat-transfer properties. For applications involving emulsion-based PCR amplification, the system and method provide improved uniformity in emulsion amplification and can be used to amplify large or small volume emulsions rapidly and reproducibly.
Abstract:
A pipette tip and system for aspiration of a biological sample, distribution to a plurality of sample chambers, and thermal cycling in the pipette tip.
Abstract:
Systems and methods for multiple analyte detection include a system for distribution of a biological sample that includes a substrate, wherein the substrate includes a plurality of sample chambers, a sample introduction channel for each sample chamber, and a venting channel for each sample chamber. The system may further include a preloaded reagent contained in each sample chamber and configured for nucleic acid analysis of a biological sample that enters the substrate and a sealing instrument configured to be placed in contact with the substrate to seal each sample chamber so as to substantially prevent sample contained in each sample chamber from flowing out of each sample chamber. The substrate can be constructed of detection-compatible and assay-compatible materials.
Abstract:
A device for performing biological analysis may include at least one reaction chamber configured to receive at least one sample for biological analysis and a thermal system configured to modulate a temperature of the at least one reaction chamber to cycle a temperature of the at least one biological sample. The thermal system may include a cooling system configured to cool the at least one reaction chamber. The cooling system may include a cooling fluid source positioned distally from the at least one reaction chamber, the cooling fluid source being in flow communication with at least one conduit configured to flow cooling fluid from the cooling fluid source to at least one location in thermal communication with the at least one reaction chamber.
