Modification Highlight: ZEN™ Internal Quencher

Use of the ZEN Quencher as a second, internal quencher in qPCR 5’-nuclease assay probes provides greater overall dye quenching, lowering background, and increasing signal detection. When incorporated into oligonucleotides, it also serves to strengthen duplex formation and block exonuclease digestion, while remaining nontoxic to cells. Thus the ZEN Quencher can be useful in steric blocking antisense oligonucleotide applications.
