Reagents utilizing a serinol scaffold for labeling synthetic oligonucleotides

Novel CE-phosphoramidites and CPG reagents have been synthesized from a serinol backbone. These reagents are useful to introduce functional groups or directly label oligonucleotides. The versatile serinol scaffold allows for labeling at any position (5′ or 3′ termini, or any internal position) durin...

More Information
Summary:Novel CE-phosphoramidites and CPG reagents have been synthesized from a serinol backbone. These reagents are useful to introduce functional groups or directly label oligonucleotides. The versatile serinol scaffold allows for labeling at any position (5′ or 3′ termini, or any internal position) during automated DNA synthesis. Multiple labels or functional groups can be achieved by repetitive coupling cycles. Optimal spacer arms and protected label moieties have been specially designed. Further, the natural 3-carbon atom internucleotide phosphate distance is retained when inserted internally.
