- 8. A composition for use in assaying biological molecules comprising a substrate to which are bound first molecules complementary to second molecules on a portion of the surface of said substrate, said second molecules being said biological molecules, the balance of the surface of said substrate having bound thereto third molecules, similar to the first molecules, but not complementary to the second molecules, and fourth molecules, also complementary to the second molecules and labeled with a daylight fluorescent pigment.

13. A composition for use in assaying of biological molecules including:
-
(a) a plurality of first molecules complementary to second molecules to be assayed, said second molecules being said biological molecules, the first molecules being bound to the surface of a convoluted substrate in a container; (b) the binding sites of the first molecules are saturated with third molecules which are the second molecules or analogues thereof; and (c) the third molecules are covalently bound to the surfaces of daylight fluorescent pigmented microparticles.
