<p>Assay apparatus comprises a first assay zone constituted by a foam pad (26) on a first solid support component (10) constituted by a plastics card having a channel (14) on one face thereof bordered by undercut walls (12) receiving a plastics slide (18) as a second solid support component having as a second assay zone a window (24). The support components fit together for relative sliding movement such that said zones are slidable with respect to one another from a first position in which said zones are separated from one another to a position in which said zones are brought into mutual contact by sliding motion. An antibody may be bound to the foam pad. An enzyme antibody conjugate may be unbound on the pad. An assay reagent which takes part in an observable reaction with the conjugate or a species to be assayed is present beneath window (24).</p> |
