摘要:
A method of detecting binding between first member or members of a binding pair and corresponding second member or members of the binding pair is disclosed. The method comprises interacting a solid support onto which the first member or members of the binding pair being immobilized and arrayed with the corresponding second member or members of the binding pair, the corresponding second member or members of the binding pair being directly or indirectly tagged with a heavy atom; and determining a spatial distribution of the heavy atom over a surface of the solid support, thereby detecting the binding between the first member or members of the binding pair and the corresponding second member or members of the binding pair.
