本発明の例示を以下に示すが、光源や容器の素材種類や容器の形状や流路形状は、例示に示す方法に限定されるものではない。
Illustrative examples of the present invention are shown below. However, the light source, the material type of the container, the shape of the container, and the shape of the flow path are not limited to the methods shown in the examples.

図1に示したように、本発明の実施形態である装置に用いる反応容器は、金型で作製した石英素材の反応容器1と、その反応容器内において、螺旋状である毛細管流路2と、試料導入口3で構成される。反応容器の全体形状は、図1では、立方体を支援したが、底面が円状の円柱状であっても、三角柱や六角柱など、底面が多角形の形状のものであってもよい。
As shown in FIG. 1, the reaction vessel used in the apparatus according to the embodiment of the present invention includes a quartz reaction vessel 1 made of a mold, and a capillary channel 2 that is spiral in the reaction vessel. And the sample inlet 3. In FIG. 1, the overall shape of the reaction vessel is a cube, but it may be a cylindrical column with a circular bottom surface or a polygonal bottom surface such as a triangular prism or a hexagonal column.

図2に示したように、本発明の装置の主要な構造は、反応容器1と、反応容器1の螺旋状の毛細管流路部分を加温設定できるように、反応容器1を収納できる構造を持つホルダー4と、そのホルダーに挿入設置された反応容器の1つの側面をDNAの変性温度で例えば95℃に温度設定するためのヒーター5、毛細管流路の流れ方向に沿った、反応容器の別の側面をプライマーがアニールする温度で、例えば55℃に温度設定するためのヒーター6、反応容器のもう一つの側面を伸長反応する温度で、例えば72℃に設定するためのヒーター7を有し、かつ、増幅した試料を紫外線励起するための光源LED8を配置し、試料から発せされる蛍光を測定する為の受光ダイオード9を配置できる構造である。 As shown in FIG. 2, the main structure of the apparatus of the present invention is a structure that can accommodate the reaction vessel 1 so that the reaction vessel 1 and the spiral capillary channel portion of the reaction vessel 1 can be heated. Holder 4, a heater 5 for setting the temperature of one side of the reaction vessel inserted and installed in the holder to a denaturation temperature of DNA, for example, 95 ° C., and the reaction vessel along the flow direction of the capillary channel A heater 6 for setting the temperature of the side surface of the reaction vessel to 55 ° C., for example, and a heater 7 for setting the temperature to the other side of the reaction vessel, for example, 72 ° C. In addition, a light source LED 8 for exciting the amplified sample with ultraviolet light is disposed, and a light receiving diode 9 for measuring fluorescence emitted from the sample can be disposed.

試料導入の方法は、試料導入口3に、増幅反応溶液に混合した測定対象試料を載せて、ポンプから増幅反応溶液を任意の速度で送液することで、反応容器の毛細管流路内に導入させ、以降、ポンプの液押し出しにより、試料を、毛細管流路内を移動させて、増幅反応を進行させる。
The sample introduction method is such that the sample to be measured mixed with the amplification reaction solution is placed on the sample introduction port 3, and the amplification reaction solution is fed from the pump at an arbitrary speed to be introduced into the capillary channel of the reaction vessel. Thereafter, the sample is moved in the capillary channel by liquid extrusion of the pump, and the amplification reaction is allowed to proceed.

試料導入口部分に、試料貯留の空間を設けて、増幅反応溶液を試料貯留の空間に導入して、試料貯留の空間内で、試料と増幅反応溶液を希釈混合させつつ、試料貯留の空間内の液の一部を反応容器内の毛細管流路内に導入を行なうことで、導入試料の連続的な希釈を行うことができる。
A sample storage space is provided at the sample inlet, the amplification reaction solution is introduced into the sample storage space, and the sample and the amplification reaction solution are diluted and mixed in the sample storage space. By introducing a part of the solution into the capillary channel in the reaction vessel, the introduced sample can be continuously diluted.

試料の希釈導入により、試料中の増幅対象DNAの濃度が変化するので、反応容器の螺旋状毛細管流路内の増幅試料由来の増幅信号の発生位置・強度が変化する。その変化情報と、希釈倍率・希釈速度、毛細管流路内の反応溶液の送液量などの情報を組み合わせることにより、試料中の増幅対象のDNAの濃度が正確に測定できる。
Since the concentration of DNA to be amplified in the sample is changed by introducing the sample into the dilution, the position and intensity of the amplification signal derived from the amplified sample in the spiral capillary channel of the reaction vessel are changed. The concentration of DNA to be amplified in the sample can be accurately measured by combining the change information with information such as the dilution rate / dilution speed and the amount of the reaction solution in the capillary channel.

反応試料と遺伝子増幅反応溶液との混合比率は、反応試料が反応容器内の毛細管流露に流入するに従い、希釈倍率が高くなり、反応容器の毛細管流路の螺旋の回転数が増加しても、増幅された遺伝子が少なくなるため、蛍光色素の信号が低下し、希釈比率が大きくない反応操作初期に反応容器の毛細管流路に導入された試料での蛍光強度と比較しながら、定量的に、試料中に存在する対象とする遺伝子の数が推定される。
The mixing ratio of the reaction sample and the gene amplification reaction solution is such that, as the reaction sample flows into the capillary flow in the reaction vessel, the dilution rate increases, and even if the spiral rotation speed of the capillary channel of the reaction vessel increases, Since the number of amplified genes decreases, the fluorescent dye signal decreases and the dilution ratio is not large. While comparing with the fluorescence intensity in the sample introduced into the capillary channel of the reaction vessel at the initial stage of the reaction operation, quantitatively, The number of genes of interest present in the sample is estimated.

遺伝子増幅を行う対象試料は、反応容器とポンプ部分の間に導入され、ポンプの送液の作用により、反応容器内の毛細管流露に導入される。
The target sample to be subjected to gene amplification is introduced between the reaction container and the pump part, and is introduced into the capillary flow in the reaction container by the action of the pump solution.
