  • Patent number: 10444230
    Abstract: A method of determining kinetic parameters for a reversible molecular interaction between a ligand immobilized to a solid support surface and a binding partner to the ligand in solution, comprises sequentially, without intermediate regeneration or renewal of the immobilized ligand, flowing a plurality of fluid volumes containing different known concentrations of the binding partner over the solid support surface, monitoring the momentary amount of binding partner bound to the solid support surface related to time and solution concentration of binding partner and collecting the binding data, and determining the kinetic parameters by globally fitting a predetermined kinetic model for the interaction between the binding partner and the immobilized ligand to the collected binding data, which model allows for mass transport limitation at the solid support surface.

  • Patent number: 7642058
    Abstract: The invention relates to a method of characterizing interaction between two species in a liquid environment, wherein a liquid comprising said at least one species is passed as a flow through a measurement system, and wherein the interaction takes place within said measurement system. The method comprises generating a concentration gradient of at least a first one of said species or of at least one other species having an influence on the interaction or on interacted components. The flow of liquid is passed through a sensor device, and a result of interaction between said at least two species is detected. The flow of liquid is intersected at least once with a further liquid before the flow is passed through said sensor, so as to create at least two separated liquid segments having different concentrations of at least one of said species forming the concentration gradient.
