Toward the expansion of the genetic alphabet of DNA, we present highly efficient unnatural base pair systems as an artificial third base pair for PCR. Hydrophobic unnatural base pair systems between 7-(2-thienyl)imidazo[4,5-b]pyridine (Ds) and 2-nitro-4-propynylpyrrole (Px) were fine-tuned for efficient PCR, by assessing the amplification efficiency and(More)
For the site-specific labeling and modification of RNA by genetic alphabet expansion, we developed a PCR and transcription system using two hydrophobic unnatural base pairs: 7-(2-thienyl)-imidazo[4,5-b]pyridine (Ds) and 2-nitro-4-propynylpyrrole (Px) as a third pair for PCR amplification and Ds and pyrrole-2-carbaldehyde (Pa) for the incorporation of(More)
