摘要:
The present invention relates to methods for monitoring in a high through-put fashion a multitude of molecular reaction processes, using a substrate, said substrate comprising a plurality of micro-channels, wherein each micro-channel has inlet and outlet open ends on opposing sides of said substrate, and wherein said micro-channels comprise at least one first reaction component, comprising the steps of: (a) contacting said micro-channels of said solid substrate with a sample, said contacting being via said inlet open ends, wherein said sample comprises an analyte, under conditions that allow said analyte to be specifically retained within said micro-channels by said first reaction component; (b) optionally removing excess of sample via said outlet open ends; (c) contacting the retained analyte with at least one second reaction component, said second reaction component being different from said first reaction component as defined in step (a), under conditions that allow a molecular reaction to take place, said reaction producing a signal; (d) detecting said signal and reading-out reaction results;(e) removing second reaction components via said outlet open ends; (f) repeating steps (c) to (e) at least once, wherein said at least one second reaction component as defined in (c) may be changed in composition; and, final detecting and reading-out of reaction results. The present invention also relates to the uses thereof as well as to microarrays and kits for performing said methods of the invention.
摘要:
The invention relates to methods and corresponding arrays especially suited to correct for signal errors due to variations in sample preparation. Methods and compositions for performing quantitative array-based assays are provided. In the subject methods, both a reporter and an analyte is employed, where the reporter is characterized by binding selectively to an internal reference present on the array, i.e. at least a subset of, if not all of, the spots present on the array employed in the method contain an internal reference which can be bound by reporter.

The present invention relates to methods for identifying analyte nucleic acids present in a sample comprising nucleic acid molecules, said method comprising the steps of: (a) providing a porous substrate, said substrate comprising a plurality of micro-channels, wherein said micro-channels have immobilized thereon a target molecule capable of binding to an analyte present in said sample; wherein said channels are further provided with analyte amplification components, a reporter system; and said sample; (b) amplifying analyte nucleic acid molecules present within said sample; and (c) allowing binding to take place between an amplified analyte nucleic acid obtained in step (b), said target molecule immobilized onto the channels of said substrate and said reporter system, wherein said reporter system allows detecting whether binding has occurred between said target molecule and said analyte nucleic acid. The present invention further relates to the use of said methods as well as kits for carrying out said methods.
摘要:
The present invention relates to methods for identifying analytes in a sample comprising the steps of: (a) incubating said analytes with a plurality of bipartite capture probes, said capture probes being immobilized in predefined regions on a solid substrate, and each capture probe consisting essentially of a first fragment which is at one end immobilized to said substrate and at the other end is complementary linked to a second fragment, wherein said second fragment comprises an extension fragment capable of identifying an analyte; (b) monitoring complex formation between sample analytes and extension fragments; (c) sequentially modifying complex formation conditions; allowing the release of captured analyte molecules from the substrate; and (d) detecting and identifying the released analytes. The present invention also relates to different uses of said methods as well as microarrays and kits for performing said methods.
摘要:
A substrate plate comprises a microplate (1) made of a plastic material, having an array of wells (2) arranged in rows and columns, the bottom of at least one well (2) being provided by a porous substrate (3). Each porous substrate (3) is incorporated into the well (2) by means of a thermal bond.
