title: Synthesis of phosphate-branched oligonucleotides.
abstract: A solid-phase synthesis for phosphate-branched oligonucleotides is described. The method is based on coupling of a single nucleoside phosphorodiamidite to terminal hydroxyl functions of two solid-supported oligonucleotides. After oxidation of the phosphite triester obtained to a phosphate triester, the third branch is assembled by conventional phosphoramidite chemistry.
