<p>A process for determining binding parameters, including dissociation constants and sorption rate constants, of the binding between a biomolecule and a binding partner thereof, both being present in a liquid phase, and comprising a marker-free binding step, characterised by the following steps: (a) attaching either (a1) the binding partner, or (a2) the biomolecule, to a solid surface (b) allowing binding between the binding partner and the biomolecule, both in the liquid phase and on the solid surface (c) attaching a marker to: (c1) the biomolecule, if said binding partner was attached to the solid surface according to step (a1), or to (c2) the binding partner, if said biomolecule was attached to the solid surface according to step (a2) (d) allowing the marker to produce a precipitate; and (e) detecting said precipitate as it is formed on said solid surface by determining a change of surface mass on the solid surface due to the formation of said precipitate. <IMAGE></p> |
