Specific double-stranded probes for homogeneous detection of nucleic acid and their application methods

摘要

Double-stranded nucleic acid hybridization probes comprise a longer strand perfectly complementary to a preselected target sequence in an assay and a shorter second strand complementary to the longer strand. The strands are labeled with interactive labels such as a fluorophore and a quencher. The probes may be used in real-time amplification assays to distinguish among alleles.
