    摘要: A reagent tube configured with a stellated shaped pattern, on its bottom interior surface, configured to facilitate complete or near-complete withdrawal of fluid from the tube, via a pipette tip. The reagent tube may be used for transporting reagents and for carrying out processing operations on biological samples with the reagents, such as preparing polynucleotides extracted from the sample for amplification.

    摘要: A system and method for preventing or reducing unwanted heat in a microfluidic of the device while generating heat in selected regions of the device.In one example, current is supplied to a heating element through electric leads, wherein the leads are designed so that the current density in the leads is substantially lower than the current density in the heating element. This may be accomplished using conductive leads which have a cross-sectional area which is substantially greater than the cross-sectional area of the heating element.In another example, unwanted heat in the microfluidic complex is reduced by thermally isolating the electric leads from the microfluidic complex. This may be accomplished by running each lead directly away from the microfluidic complex, through a thermally isolating substrate. After the leads pass through the thermally isolating substrate, they are then routed to the current source. Thus, the thermally isolating substrate substantially blocks the transfer of heat from the leads to the microfluidic complex.In another example, unwanted heat is removed from selected regions of the microfluidic complex using one or more cooling devices. One or more Peltier cooling devices may be attached to a substrate to remove heat generated by heating elements and/or other electronic circuitry.

    摘要: The present invention relates to an electrochemical method for detecting a target polynucleotide. An electrode comprising an electrode surface is provided. The electrode surface includes at least one probe molecule reverisbly immobilized with respect to the electrode surface. A first electrochemical signal indicative of an amount of probe molecule immobilized with respect to the electrode surface is obtained. The electrode surface is contacted with a liquid comprising the target polynucleotide. Upon the contacting step, at least some of the probe molecule immobilized with respect to the electrode surface dissociates therefrom. A second electrochemical signal indicative of an amount of probe molecule immobilized with respect to the electrode surface is obtained. The presence of the target polynucleotide is determined at least partially on the basis of the first and second electrochemical signals.
