Dual Labeled Fluorescent Probes

Real-Time PCR Dual Labeled Probes

Dual Labeled Fluorescent Probes are DNA oligonucleotides of 20-30 bp carrying a fluorophore (5'-end) and a quencher (3'-end). The labeled probe hybridizes sequence-specifically to its complementary section of the amplicon. During DNA extension of each PCR cycle, the fluorophore reporter is being cleaved and released. The resulting, detectable fluorescence signal is proportional to the amount of accumulated PCR product. All labeled probes are purified by HPLC and quality checked by MALDI-TOF. Select from Jena Bioscience’s extensive reporter/quencher repertoire or inquire for alternative combinations (info@jenabioscience.com).
