<p>A biochemical detection method in which a ligand is bound to a surface, an aqueous solution containing an anti- ligand is brought into contact therewith whereby antiligand becomes bound to ligand, the aqueous solution is separated from the thus bound antiligand, and the antiligand is detected using a detection means associated therewith, for example using amplified enzyme-linked immunoassay.</p><p>The surface is treated with at least one agent for limiting non-specific binding of either the ligand orthe antiligand with other substrates, which agent is
