Abstract: | Abstract The syntheses of pyrrole-oligonucleotide-peptide conjugates and pyrrole-oligonucleotide-biotin conjugates were described. The oligonucleotide moiety acted as an ?active linker? which allowed the easy purification and quantitation of the conjugates and in turn controlled the grafting. The peptide conjugates were immobilised on silicon array and their immunoreactivity was tested using biotinylated antibodies and a phycoerythrin-streptavidin staining. The biotin conjugate provided a fluorescence scale. |
