Abstract
Binding assays are effected by introducing a specific binding reagent through a top absorbant membrane in parallel contact with a main absorbant membrane. By providing a parallel flow of liquid in the two membranes, and by controlling the flow of the diluted reagent from the top absorbant membrane into the main absorbant membrane, a controlled, uniform dilution of the reagent is obtained, leading to more accurate assay results.
