title: Rapid routes of synthesis of oligonucleotide conjugates from non-protected oligonucleotides and ligands possessing different nucleophilic or electrophilic functional groups.
abstract: Optimized methods are described for post-synthetic conjugation of non-protected oligodeoxyribonucleotides to different ligands. Methods for the terminal functionalization of oligonucleotides by amino, sulfhydryl, thiophosphate or carboxyl groups using different chemical reactions and linkers in both organic and aqueous media are described and compared. Experimental conditions for subsequent coupling of ligands containing aliphatic and aromatic amines, aromatic alcohols, carboxylic, sulfhydryl, alkylating, aldehydic and other reactive nucleophilic and electrophilic groups to oligonucleotides were established, including covalent linkage to other oligonucleotides.
