Reaction vessel.

摘要

A reaction vessel for microassay is provided. The reaction vessel comprises a body structure having provided therein at least one reaction unit comprising 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. By using the present reaction vessel, an assay at high precision may be carried out by a simple operation.
