Abstract:
The present disclosure provides methods, compositions and kits as well as systems for manipulating nucleic acids, including implementing isothermal amplification, such as recombinase-polymerase amplification (RPA), of a nucleic acid template using a pre-seeded solid support. Provided are rapid and efficient methods for generating template nucleic acid molecules comprising specific nucleotide sequence bound to solid support. Such methods can be used, for example, in manipulating nucleic acids in preparation for analysis methods that utilize monoclonal populations of nucleic acids.
Abstract:
The disclosure generally relates to systems, methods, and apparatuses for magnetic bead loading. An example embodiment of the disclosure relates to mixing magnetic beads with sequencing beads to form a solution. The solution containing both beads is injected onto a microchip having a plurality of microwells. The magnetic beads may have larger diameter than the microwell while the sequencing beads may have a smaller diameter, allowing them to enter and reside in the microwell. One or more magnets positioned under the microchip move back and forth across the microchip surface. The magnetic beads form a line and follow the movement of the magnets. During rounds of sweeping, the sequencing beads load into the respective wells. The magnets may be disengaged and the magnetic beads may be washed away after the sequencing beads are loaded.
Abstract:
A sensor component includes a sensor including a sensor surface and a reaction site in cooperation with the sensor and exposing the sensor surface. The reaction site including a reaction site surface. A surface agent is bound to the reaction site surface or the sensor surface. The surface agent includes a surface active functional group reactive with Bronsted base or Lewis acid functionality on the reaction site surface or the sensor surface and including distal functionality that does not have a donor electron pair.
Abstract:
A sensor apparatus includes a substrate, a semiconductor device (such as a chemFET or ion-sensitive FET) disposed over the substrate, the semiconductor device having a surface electrode structure, and a saccharide coating formed over the surface electrode structure. The saccharide coating can be removed prior to use, e.g., in nucleic acid sequencing. The semiconductor device can include a well and optionally a bead conjugated to a nucleic acid disposed in the well.
Abstract:
A method of forming a polymer matrix array includes applying an aqueous solution into wells of a well array. The aqueous solution includes polymer precursors. The method further includes applying an immiscible fluid over the well array to isolate the aqueous solution within the wells of the well array and polymerizing the polymer precursors isolated in the wells of the well array to form the polymer matrix array. An apparatus includes a sensor array, a well array corresponding to the sensor array, and an array of polymer matrices disposed in the well array.
Abstract:
An apparatus includes a substrate, a gate structure disposed over the substrate and having an upper surface, a well structure disposed over the substrate and defining a well over the upper surface of the gate structure, a conductive layer disposed on the upper surface of the gate structure and at least partially extending along a wall of the well in the well structure, and a dielectric structure disposed over the well structure and defining an opening to the well.
Abstract:
A method of loading beads on a sensor substrate includes applying a suspension including beads to a flow cell defined over a sensor substrate. The sensor substrate includes a plurality of wells. The beads at least partially deposit into the plurality of wells. The method also includes removing liquid from the flow cell, evaporating liquid from the flow cell, for example, by drawing air through the flow cell; and applying a hydrating solution to the flow cell.
