Abstract:
1. An analytical system comprising: a support member having a plurality of chemically active receptors thereupon, wherein said receptors are grouped within an array of spots, said spots with a functional size of 5 micrometers to 400 micrometers, said spots separated with a functional distance from each other, wherein said functional distance is 10 to 200 percent in value of the diameter of said spots; each of said spots comprising at least one of a plurality of different first members each immobilized on an uppermost surface of said support, said first members being selected from the group consisting of: protein, peptide, polysaccharide, cell fragments, cells, tissue, organometallics, metal ion chelating organic ligands, and combinations thereof, said first members each being capable of binding to a member of a plurality of different complementary second members to form a specific binding pair; a peroxidase enzyme; and a conjugate of a label and a substituted phenol substrate for said enzyme, said substrate being activatable by said enzyme so as to cause said substrate to bind to one of said chemically active receptor sites whereby said substrate and said label are immobilized upon said support member.
