Abstract
A reaction vessel for microassay is provided. The reaction vessel has a body structure having provided therein at least one reaction unit having a channel having at least one fluid inlet and at least one reagent-immobilized area in the downstream of the fluid inlet. The channel is provided with a vent mechanism, and the reagent-immobilized area has a reagent fixedly immobilized thereto. The results of the assay are indicated in the reagent-immobilized area. The channel may be provided with a reagent-attached area wherein a reagent is tentatively attached so that the reagent may dissolve into the fluid flowing over the area. The channel may be also provided with a fluid sump for retaining the fluid within the reaction vessel. A rocking base allows the vessel to become inclined as the downstream sump moves downward when the fluid moves into the sump. By using the present reaction vessel, an assay at high precision may be carried out by a simple operation.
