摘要
The highly selective detection of homopurine target strands with a triplex-forming molecular probe is described. The binding of a clamp-type oligonucleotide containing two terminally attached pyrene molecules to the target sequence is easily monitored through excimer formation. The oligonucleotide probe allows the efficient discrimination of single nucleotide mismatches because of the high mismatch sensitivity of the triplex formation. © 2007 Wiley-VCH Verlag GmbH & Co KGaA.
