HYBRIDIZATION-BASED FLUORESCENCE ASSAY

摘要

The invention provides a method for detecting the presence or absence of an oligonucleotide in a sample. In the method according to the invention, a sample is obtained that may contain a target oligonucleotide. An oligonucleotide that is complementary to the target oligonucleotide and a fluorophore are added to the sample to form a mixture. The mixture is then incubated under hybridization conditions to allow binding of the complementary oligonucleotide to the target oligonucleotide to form a duplex. The fluorophore binds to the duplex; and fluorescence is then detected by standard procedures. The detection of fluorescence is indicative of the presence of the target oligonucleotide in the sample.
