Anthracene based base-discriminating fluorescent oligonucleotide probes for SNPs typing: Synthesis and photophysical properties Original Research Article

2- and 9-Anthracenecarboxamide labeled 2′-deoxyuridines were synthesized and their photophysical properties were examined. These oligonucleonucleotide probes are capable of detecting adenine base on a target DNA sequence. It was also found that 2-anthracene based oligonucleotide probe is more efficient than the corresponding 9-anthracene based oligonucleotide in the application for DNA chip based SNP detection, due to its longer emission wavelength and high fluorescence intensity.
