Abstract
A device for performance of ligand-receptor assay methods for determining the presence of a ligand. The preferred ligand-receptor pair are antigen-antibody pairs. The device has a membrane having the receptor physically bound to its surface. A closable gap exists between the membrane and an absorbent means. Substantially all of the top surface of the membrane is exposed. The device has a piston means disposed inside the body member, and in air-tight seal with the body member. Means to actuate the piston means are disposed outside the body member. The piston means creates a region of reduced pressure.
