  • Labelled oligonucleotides synthesized on solid-supports
    Publication number: 20050191660
    Abstract: Methods and compositions to label oligonucleotides and analogs directly on a solid-support having the structure where S is a solid-support, A is a cleavable linker, X is a moiety with three or more attachment sites, L is a label, Y is a nucleophile, i.e. O, NH, NR or S, and P1 is an acid cleavable protecting group are provided. The labelled solid-support is reacted in a cyclical fashion to synthesize a labelled oligonucleotide on a solid-support in the 5? to 3? direction, having the structure: Labelled oligonucleotides are also synthesized by reacting: (i) a label reagent bearing functionality consisting of carboxylic acid, sulfonic acid, phosphonic acid, or phosphoric acid, (ii) an oligonucleotide on solid support with nucleophilic functionality, and (iii) a coupling reagent, whereby an ester, amide, thioester, sulfonamide, sulfonate, phosphonate, phosphoramidate, phosphorothioate, or phosphate bond is formed.
