摘要:
A reactive solid carrier favorably employable for manufacturing DNA chip is composed of a solid carrier and a plurality of vinylsulfonyl groups or their reactive precursors each of which is fixed onto a surface of the solid carrier by covalent bonding via a linking group, and a method for producing a DNA chip is performed by bringing the reactive solid carrier into contact with nucleotide derivatives or their analogues having a reactive group which is reactive with the vinylsulfonyl group or reactive precursor fixed to the solid carrier.

摘要:
An object of the present invention is to provide a microchip whereby, when chemical analysis is conducted, a specimen liquid can be directly collected and weighed without using any collecting and weighing devices. The present invention provides a microchip for analyzing liquid samples, which has a measuring structure for weighing and collecting a given amount of a specimen liquid within a range of 0.05 to 10 μl from an excessive amount of the specimen liquid which was introduced in the chip, wherein the measuring structure is located at the upstream side of an analysis element for analyzing a target substance in the specimen liquid inside the microchip.
摘要:
An integrated assay chip for assaying one or more components of a specimen, which comprises: (1) one or more pretreatment elements for pretreating a specimen; (2) one or more multilayer dry assay elements capable of assaying one or more components of the pretreated specimen; and (3) one or more flow channels connecting the pretreatment element and the multilayer dry assay element is provided.
摘要:
The present invention provides a reactive microreactor wherein a group of the following formula (1) which can bind to a member of specifically binding partner, is bound to a part or entirety of a wall surface of a channel: -L-SO2—X1 (1) wherein X1 represents —CR1═CR2R3 or —CHR1—CR2R3Y; R1, R2 and R3 independently represent an atom or a group selected from the group consisting of a hydrogen atom, a C1-6 alkyl group, a C6-20 aryl group, and a C7-20 aralkyl group having a C1-6 alkyl chain; Y represents a group which can be substitutable by a nucleophilic reagent or a group which is released as “HY” by a base; and L represents a linking group. The microreactor according to the present invention has advantages that it requires a less amount of a reagent and achieves a higher S/N ratio.
