Abstract: | Abstract Several biotinylated synthetic oligodeoxyribonucleotides have been selectively prepared by a simple and efficient chemical method. This procedure allows the specific and covalent coupling of one biotinmoiety to any 5′-kinased unprotected oliqodeoxyribonucleotide through an aminoalkylphosphoramide linker arm. The reactions are performed in aqueous solutions on unprotected oligonucleotides and proceed cleanly with good yields. This method is insensitive of the length of the polynucleotide, of the nucleotide sequence and of the nature of the 5′-terminal nucleotide. |
