Abstract

The invention relates to a device for performing immunological, histochemical and cytochemical, molecular biological, enzymological, clinical-chemical and other analyzes, wherein the device comprises an object holder having one or more elongate adhesive surfaces and a reagent holder having one or several channels. The object holder is detachably connectable to the reagent holder in such a manner that the elongate adhesive surfaces each face one of the channels and, when reaction partners bound to a solid phase are disposed on the elongate adhesive surfaces and reactants dissolved in liquid are present in the channels, the reaction partners and the reactants are in contact. Means are provided for preventing the liquid from passing from one channel into an adjacent channel. A method for performing a corresponding analysis can be performed with this device, by connecting the object holder to the reagent holder in such a manner that the elongate adhesive surfaces each face a channel, liquid having reactants dissolved therein is introduced into the channels such that the solid phase substrates having reaction partners bound thereto and being disposed on the adhesive surfaces come into c…
