Abstract:
An analytical system comprising:a support member having a plurality of chemically active phenolic or proteinaceous receptor sites hereupon; an array of different first members of a specific binding pair disposed on said support, said first members being selected from the group consisting of DNA, cDNA, RNA, oligonucleotides, and combinations thereof, said first members each being capable of binding to a complementary second member of said specific binding pail, whereby when said array is contacted with a plurality of analyte complementary second members, a plurality of specific binding pairs will be formed on said support; a peroxidase enzyme; a coupling agent operative to couple said enzyme to said specific binding pairs;and a conjugate of a labelling agent 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 labelling agent are immobilized upon said support.
