Nucleic acid probe containing fluorescent tricyclic base-linked acyclonucleoside for detection of single nucleotide polymorphisms

The development of a reliable and simple method for detecting single nucleotide polymorphisms (SNPs), common genetic variations in the human genome, is currently an important research area because SNPs are important for identifying disease-causing genes and for pharmacogenetic studies. Here, we developed a novel method for SNP detection. We designed and synthesized DNA probes containing a fluorescent tricyclic base-linked acyclonucleoside P. The type of nucleobases involved in the SNP sites in the DNA and RNA targets could be determined using four DNA probes containing P. Thus, this system would provide a novel and simple method for detecting SNPs in DNA and RNA targets.
