ABSTRACT:
The invention relates to an assay method and a fluid microsystem for carrying out said assay method, in particular, for carrying out miniaturized affinity tests in a micro-array format. According to said invention, a liquid phase comprising at least one type of detectable high-molecular weight soluble substance, for example a labeled reaction partner or product of an affinity reaction is displaced by the hydraulic effect of a high-molecular weight osmotic agent on an ultrafiltration membrane towards a miniaturized measuring chamber defined thereby. The fraction of the detectable high-molecular weight substance(s) is concentrated in the measuring chamber, while the dissolved low-molecular weight components are removed with the solvent through the membrane pores, thereby making it possible to attain a high detection sensitivity.
