Problems solved by technology

[0007] However, in the case of providing reagents from the outside, a plurality of reagents must be prepared separately from the biochemical reaction cartridge, and if the number of test items is large, the required reagents The number of
Therefore, reagent updating becomes complicated and reagent species may be incorrectly selected
In addition, in the case of storing reagents in the chambers of the biochemical reaction cartridge, there is a possibility that the reagents in the chambers flow into the channel or another chamber due to environmental changes at the time of storage or transportation. chamber to produce a different response than expected

Embodiment Construction

[0033] The present invention will be described in more detail below with reference to these drawings.

[0034] figure 1 is a perspective view of the biochemical reaction cartridge in this embodiment. refer to figure 1 , the cartridge has a double-layer structure comprising a reaction part 1 for carrying out a reaction and a solution storage part 2 provided thereon for storing a solution such as a reagent and a cleaning agent.

[0035] The main body of each of the reaction part 1 and the solution storage part 2 is made of synthetic resin such as polymethylmethacrylate (PMMA), acrylonitrile-butadiene-styrene (ABS) copolymer, polystyrene, polycarbonate, Made of polyester or polyvinyl fluoride. In cases where optical measurements are required, the material of the reaction part 1 body needs to be transparent or translucent plastic.

[0036] At the upper part of the reaction part 1, a sample port 3 for injecting a sample such as blood by a syringe (injector) is provided, and i...

Abstract

A biochemical reaction cartridge includes a reaction portion, comprising a chamber and a passage, for effecting a biochemical reaction, and a solution storage portion, which is isolated or separated from said reaction portion, for storing a solution in a position corresponding to the chamber. The cartridge is provided with a penetrable partition member disposed between said solution storage portion and said reaction portion so as to move the solution from said solution storage portion to the chamber of said reaction portion. The biochemical reaction cartridge is incorporated in a biochemical reaction apparatus.

Description

technical field [0001] The present invention relates to a biochemical reaction cartridge to be contained in an apparatus for analyzing cells, microorganisms, chromosomes, nucleic acids, etc. in a sample by utilizing a biochemical reaction such as antigen-antibody reaction or nucleic acid hybridization. Background technique [0002] Most analyzers for analyzing samples such as blood employ an immunological method utilizing antigen-antibody reactions or a method utilizing nucleic acid hybridization. For example, a protein such as an antibody or an antigen or a single-stranded nucleic acid specifically linked to a material or substance to be detected is used as a probe and immobilized on a solid surface such as a fine particle, a bead, or a glass plate, thus realizing an antigen-antibody reaction or a nucleic acid hybridize. Then, for example, the antigen-antibody mixture or double-stranded nucleic acid is detected by labeled antibody or labeled nucleic acid, which can produce...
