摘要: An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path.

摘要: An apparatus for controlling the temperature of a reaction mixture contained in a chamber of a reaction vessel comprises a thermal surface for contacting a flexible wall of the chamber and an automated machine for increasing the pressure in the chamber. The pressure increase in the chamber is sufficient to force the flexible wall to conform to the thermal surface for good thermal conductance. The apparatus also includes at least one thermal element for heating or cooling the surface to induce a temperature change within the chamber.

摘要: A cartridge (101) for separating a desired analyte from a fluid sample includes a sample port (103) and a sample flow path extending from the port through the body of the cartridge. The sample flow path includes at least one flow-through component (122), e.g., filter paper or a microfabricated chip, for capturing the desired analyte from the sample as the sample flows through the cartridge. The cartridge also includes an elution flow path for carrying elution fluid through the component (122) to release captured analyte from the component into the elution fluid. The elution flow path diverges from the sample flow path after passing through the component (122). Flow controllers (41A) and (41B) direct the remaining fluid sample into a waste chamber (139) after the sample flows through the component (122) and direct the elution fluid and eluted analyte into a reagent chamber (141) and reaction chamber (143). The continuous-flow design of the cartridge permits the rapid processing of a fluid sample that is larger in volume than any interactive region within the cartridge, allowing increased sensitivity in the detection of low copy concentrations of analytes, such as nucleic acid.

摘要: A reaction vessel having a reaction chamber for holding a sample is fabricated by producing a housing having a rigid frame defining the minor walls of the chamber. The housing also defines a port for introducing fluid into the chamber. At least one sheet or film is attached to the rigid frame to form at least one major wall of the chamber. In preferred embodiments, two sheets or films are attached to opposite sides of the rigid frame to form two opposing major walls of the chamber, the major walls being connected to each other by the minor walls.

摘要: A system for controlling the temperature of a reaction mixture comprises at least one heating device for heating the mixture and a power regulator for regulating the amount of power supplied to the heating device. A controller in communication with the power regulator includes program instructions for heating the reaction mixture by setting a variable target temperature that initially exceeds a desired setpoint temperature for the mixture. When the heating device reaches a threshold temperature, the variable target temperature is decreased to the desired setpoint temperature. In another embodiment, the controller includes an adaptive control program for dynamically adjusting the duration or intensity of power pulses provided to the heating device.
