  • Patent number: 5840879
    Abstract: The invention provided methods and compositions for oligonucleotide synthesis and labeling. The subject compounds have either rigid ring or long linear linker structures and provide enhanced coupling efficiencies over prior art labeling reagents because of lack of stereo hindering and/or provide more convenient and cost-effective syntheses. These novel linkers also contain a base labile structure which provides: labeling at 3' end with regular solid supports, cleaving under mild conditions, and achieving higher yield because of the complete cleavage and higher purity because the mild conditions will not bring down the impurities on the solid support. When used in a solid support pre-attached with either a nucleotide for unlabeled oligonucleotide synthesis, or a label for 3' end labeled oligonucleotide synthesis, or an alternate structure to use as an universal support, these linkers provide solid supports requiring only mild cleavage conditions.
