    摘要: The present invention relates a device for the efficient binding of nucleic acids on a microarray, comprising a reaction zone comprising a microarray, and a capture zone comprising a porous membrane substrate, wherein the capture zone is capable of specifically capturing sense strands of target molecules, whereas complementary antisense strands are captured in the reaction zone, or vice versa. The invention further envisages temperature regulating units in the device allowing to bring or keep the capture at a temperature not allowing hybridizing or binding of nucleic acid(s) to the capture molecules or to a temperature suitable for nucleic acid hybridization. The invention also relates to a method of efficiently binding nucleic acids on a microarray, comprising introducing a medium containing one or more target molecules in denatured form into a capture zone of a device of the present invention, performing an interaction reaction between the target molecules and immobilized capture molecules in said capture zone, and transporting not bound target molecule strands to a reaction zone comprising a microarray, thereby allowing an interaction between the target molecule strands and immobilized capture molecules on the microarray. In a further aspect the invention relates to the use of such a device for enriching target molecules, specifically selecting a target molecules, expression analysis, comparative genomic hybridization, the detection of SNPs, or for microarray-based genomic selection-based sequencing.

    摘要: The present invention relates to a method for performing molecular reactions in a device comprising the steps of (a) introducing one or more reagent solution(s) and an immiscible intermediate fluid into the device, wherein the device comprises a substrate, on which chemically or biochemically recognizable entities are immobilized; (b) performing molecular reactions between the immobilized chemically or biochemically recognizable entities and the reagent solution(s); or on the immobilized chemically or biochemically recognizable entities in the presence of the reagent solution(s); (c) displacing the reagent solution(s) present on the substrate by the immiscible intermediate fluid; (d) separating the immiscible intermediate fluid and the reagent solution(s); and reusing the reagent solution(s) and/or immiscible intermediate fluid for one or more repetitions of steps (a) to (e). The invention further relates to a device for performing a molecular reaction, comprising a reaction zone, reservoirs and liquid connections and a col lection and regeneration zone wherein the immiscible intermediate fluid and the reagent solution(s) are separable by gravitational separation; or a redirection and distribution module, wherein the immiscible intermediate fluid and reagent solution(s) are separated. The invention also relates to the use of an immiscible intermediate fluid for displacing a reagent solution present in a reaction zone in a microfluidic device, as well as the use of a corresponding device for performing a sequencing reaction or a nucleic acid synthesis reaction.
