ABSTRACT:
An immunoassay device and a method of performing immunoassay using this immunoassay device are disclosed. The immunoassay device includes a plate substrate having a flat surface, a plurality of adjacent projections projecting on the flat surface of the plate substrate, and a plurality of immunoreaction regions formed by applying and fixing immunoassay reagents to and in flat regions defined by the adjacent projections. The immunoreaction regions are spaced apart from each other and have surface levels equal to or higher than a surface level of the plate substrate. The immunoassay device is used to simultaneously perform various types of immunoassay and requires a simple washing for immunoassay. Specimens do not flow out from the plate or mix with each other, and safe, accurate immunoassay can be performed.
