C2'-pyrene-functionalized triazole-linked DNA: universal DNA/RNA hybridization probes.

ABSTRACT: Development of universal hybridization probes, that is, oligonucleotides displaying identical affinity toward matched and mismatched DNA/RNA targets, has been a longstanding goal due to potential applications as degenerate PCR primers and microarray probes. The classic approach toward this end has been the use of "universal bases" that either are based on hydrogen-bonding purine derivatives or aromatic base analogues without hydrogen-bonding capabilities. However, development of probes that result in truly universal hybridization without compromising duplex thermostability has proven challenging. Here we have used the "click reaction" to synthesize four C2'-pyrene-functionalized triazole-linked 2'-deoxyuridine phosphoramidites. We demonstrate that oligodeoxyribonucleotides modified with th
