摘要： A process for carrying out functional assays on test cells is described comprising the following steps: a) providing an array of measuring points which are separate from each other and to which in each case capture molecules to which said test cells can bind are immobilized, b) generating a mixture of said test cells and of reference particles which are capable of binding to said capture molecules and which are distinguishable from said test cells, c) contacting the mixture of step b) with the array so that test cells and reference particles can bind to each measuring point, and d) determining the ratio of bound test cells of interest to bound reference particles for at least some of the measuring points. In a further process, at least one measuring point with its assigned capture molecules is distributed between a plurality of measuring areas in the array, which are arranged at various sites in said array. In another process, the array is agitated, after contacting with the test cells and, where appropriate, the reference particles.
