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. The labelling reaction may be conducted at label sites including the 5′ terminus, the 3′ terminus, a nucleobase, an internucleotide linkage, a sugar, amino, sulfide, hydroxyl, and carboxyl.

Novel linkers for linking a donor dye to an acceptor dye in an energy transfer fluorescent dye are provided. These linkers facilitate the efficient transfer of energy between a donor and acceptor dye in an energy transfer dye. One of these linkers for linking a donor dye to an acceptor dye in an energy transfer fluorescent dye has the general structure R21Z1C(O)R22R28 where R21 is a C1-5 alkyl attached to the donor dye, C(O) is a carbonyl group, Z1 is either NH, sulfur or oxygen, R22 is a substituent which includes an alkene, diene, alkyne, a five and six membered ring having at least one unsaturated bond or a fused ring structure which is attached to the carbonyl carbon, and R28 includes a functional group which attaches the linker to the acceptor dye.
