1. A process for detecting or quantifying non-nucleic analytes of interest, said process comprising the steps of:
1) providing:
a) a sample comprising analytes, said analytes of the sample comprising or suspected of comprising one or more of a first non-nucleic acid analyte of interest and a second non-nucleic acid analyte of interest, wherein
said non-nucleic acid analytes comprise oligopeptides, polypeptides, oligosaccharides, polysaccharides, lipids, ligands, or combinations thereof;b) an array on a solid surface, said array comprising a plurality of discrete areas; wherein
at least two of said discrete areas comprise a first discrete area and a second discrete area, said first discrete area and said second discrete area comprising a chimeric composition consisting of a nucleic acid portion covalently bound to a non-nucleic acid portion;said nucleic acid portion of the chimeric composition located at said first discrete area has a different sequence from that of said nucleic acid portion of the chimeric composition located at said second discrete area;said covalently bound non-nucleic acid portion of the chimeric composition of said first discrete area has a binding affinity for the first non-nucleic acid analyte of interest,said covalently bound non-nucleic acid portion of the chimeric composition of said second discrete area has a binding affinity for the second non-nucleic acid analyte,said first non-nucleic acid analyte is different from said second non-nucleic acid analyte, andwhen the non-nucleic acid portion is a peptide or protein, the nucleic acid portion does not comprise a sequence which is either identical or complementary to a sequence that codes for said peptide or protein; andc) signal generating means; 2) labeling said non-nucleic acid analytes of the sample with said signal generating means; 3) contacting said array with said labeled non-nucleic acid analytes under conditions permissive of binding said labeled non-nucleic acid analytes to said non-nucleic acid portion; and 4) detecting or quantifying the presence of said first and second non-nucleic acid analytes of interest by measuring said signal generating means respectively bound to said first and second discrete areas of said array. |
