A METHOD OF REAL-TIME DETECTION OF NUCLEIC ACID SEQUENCES

摘要

A homogeneous method for detecting and/or quantifying specific nucleic acid sequences (DNA or RNA) in amplification or reverse transcription reactions, involving the use of fluorescently labeled forward and reverse primer pairs that produce a fluorescence resonance energy transfer signal when they are incorporated into the complementary strands of a double-stranded reaction product. The method includes selecting a target sequence and forming the members of the primer pair so that their fluorescent labels are in close proximity, so producing a detectable signal on receiving an energy stimulus. The method also involves selecting short nucleic acid target sequences, resulting in short amplification products in polymerase chain reactions characterized by relative short duration, high sensitivity and reduced secondary non-specific reactions.
