摘要:
A parallel processing system for processing samples is described. In one embodiment, the parallel processing system includes an instrument interface parallel controller to control a tray motor driving system, a close-loop heater control and detection system, a magnetic particle transfer system, a reagent release system, a reagent pre-mix pumping system and a wash buffer pumping system.
摘要:
Methods for normalizing output from an instrument employing a reference standard or non-fluorescing substance disposed within at least one of a plurality of reaction chambers. The method comprises collecting and analyzing a signal associated with the reference standard or non-fluorescing substance to determine a normalizing bias. The normalizing bias is then applied to the data signal collected from a remainder of the plurality of reaction chambers.
摘要:
An apparatus and methods are provided for heating and sensing the temperature of a chemical reaction chamber without direct physical contact between a heating device and the reaction chamber, or between a temperature sensor and the reaction chamber. A plurality of chemical reaction chambers can simultaneously or sequentially be heated independently and monitored separately.

The application provides sample preparation devices and analyses. The devices and analyzes allow for the rapid preparation and analysis of samples using a variety of techniques, including PCR, by even unskilled users.
摘要:
A screening device and a method are described herein which can automatically handle and measure (interrogate) a plurality of sensor carriers (i.e., multiwell plates, microplates) with multi-dimensionally arranged, temperature-compensated or temperature-compensatable optical sensors, while maintaining a substantially constant temperature gradient for a relatively long period of time around the optical sensors where temperature compensation has been performed on the sensor carriers.
摘要:
The present invention is directed to novel device comprising a sol-gel filled microchannel and methods for purifying nucleic acids from biological samples. In one embodiment shown in FIG. 1, the microfluidic device (1) comprises a base (2) with a microchannel (3) formed in the interior of base (2), wherein said microchannel (3) is filled with a sol-gel matrix and in fluid communication with an inlet port (4) and outlet port (5) wherein inlet port (4) and outlet port (5) are formed on the exterior surface (10) of base (2). The device may be further provided with additional components to allow for analytical analysis of the purified nucleic acid sequences.
摘要:
In a nucleic acid detecting cassette in which a heating treatment chamber and a liquid delivery channel are constituted of a stationary member and flexible members, the heating treatment chamber is held by convex heating sections from both sides, whereby the heat treatment chamber and the liquid delivery channel are spatially separated from each other. Thus, it is possible to automatically execute a consistent process including nucleic acid amplification and other required treatments of the object sample as well as detection of a target nucleic acid.

摘要:
A sample processing system that may be automated and methods are disclosed where samples are arranged on a carrier element and a process operation control system automatically processes the samples perhaps robotically with an operationally-influential exteriorly-consequential information monitor or a data capture element. Significant process details as well as operationally-influential exteriorly-consequential information may be monitored and an automatic notice element may cause notification of a person at some display that may be remote. Various people may be notified, such as an administrator, a supplier, or a manufacturer of an opportunity for some action such as reagent reordering or the like. A simulated motion display may be included to “watch” simulated operation in real time or long after completion of the actual processing.
摘要:
An apparatus for normalizing a PCR instrument, can comprise a microplate comprising at least 6,000 wells and a system of dyes at known concentrations in a plurality of the at least 6,000 wells. A method for normalizing a system can comprise (a) providing a microplate comprising at least 6,000 wells and a system of dyes; (b) exciting at least one dye; (c) detecting an emission output for the at least one dye; (d) determining if the emission output is in an acceptable range; and (e) adjusting the system so that the emission output is in the acceptable range.
