Apparatus for carrying out a biochemical assay, for example an immunoassay or nucleic acid hybridisation assay comprises, a hard polystyrene reaction surface adapted to bind a first biochemical ligand (e.g. a monoclonal antibody), a liquid absorbent wadding adjacent the reaction surface to absorb washing solution applied to the reaction surface, a filter matrix overlying the reaction surface in close contact therewith, for filtering a sample, and for retaining a second biochemical ligand in contact with the reaction surface, wherein the second biochemical ligand is capable of being specifically bound with the first biochemical ligand on the surface. The filter matrix is removeable to facilitate washing of the reaction surface, and the filter matrix comprises a labelled substance capable of a specific-binding reaction at the reaction surface during the assay. |
