Nucleic acid amplifier and nucleic acid inspection device employing the same
A nucleic acid amplifier comprises a holder 3 which is provided with a plurality of temperature control blocks 10 each designed to hold at least one reaction vessel 105 storing a reaction solution. The temperature of the reaction solution in each reaction vessel 105 is controlled individually by using temperature control devices 14 and 15 arranged in each of the temperature control blocks 10. The temperature that is set in each temperature control block 10 and the timing for temperature changes are controlled independently of the temperatures of other temperature control blocks 10. This configuration makes it possible to provide a nucleic acid amplifier and a nucleic acid inspection device (employing the nucleic acid amplifier) capable of processing multiple types of samples differing in the protocol in parallel (parallel processing) and starting a process for a different sample even when there is a process in execution.
Cryobag thawing methods
A consistent and repeatable thawing method of frozen samples in a bag-format storage vessel is described herein. Methods and systems may allow for multiple bag-format storage vessel sizes to be used in the same device. A subset of a plurality of sensors may be qualified for the thawing method. The method may further include heating a frozen sample using a first heater bank and a second heater bank. In addition, the method may include measuring a plurality of second temperatures of the bag-format vessel. At or slightly after a second threshold temperature, the method may include heating using the first heater bank and terminating heating using the second heater bank. The method may include terminating the heating of the partially thawed sample using the first heater bank after the partially thawed sample has been heated using the first heater bank for a duration.

An automated system for performing nucleic acid amplification assays on samples provided to the system, where the system includes data input components configured to enable input specifying one or more user-defined assay parameters; data storage media storing a first set of assay parameters, the first set of assay parameters consisting of system-defined parameters, and a second set of assay parameters, the second set of assay parameters including the one or more user-defined parameters; and command input components configured to enable input specifying (i) that a first nucleic acid amplification assay be performed on a first sample in accordance with the first set of assay parameters, and (ii) that a second nucleic acid amplification assay be performed on a second sample in accordance with the second set of assay parameters. The system further includes one or more wash stations, a fluid transfer device, a thermal processing station, and a detection station for detecting the presence or absence of multiple analytes.
METHOD AND SYSTEM FOR THERMALLY CONTROLLING A CHEMICAL REACTION IN DROPLETS
Methods and systems for thermally controlling a chemical reaction in droplets. In an exemplary method, a first thermal zone and a second thermal zone having different temperatures from one another may be created in a reaction chamber. An emulsion including droplets encapsulated by a carrier fluid may be held in the reaction chamber. The droplets may have a density mismatch with the carrier fluid, and each droplet may include one or more reactants for the chemical reaction. An orientation of the reaction chamber may be changed to move the droplets from the first thermal zone to the second thermal zone, such that a rate of the chemical reaction changes in at least a subset of the droplets.
