The Dabcyl group has been found to be a universal quencher. 3’-Dabsyl CPG and 3’-Dabcyl CPG are used to prepare probes with the quencher blocking the 3’-terminus.

With the growing popularity of red and near-infrared dyes, we are offering the Black Hole QuencherTM dyes (BHQs).

We are happy to offer several products containing the BlackBerry® Quencher (BBQ-650®), which exhibits a broad absorption profile from 550nm to 750nm, centered at 650nm.

Synthetic oligonucleotides with covalently-attached CDPI3 have enhanced DNA affinity and have improved the hybridization properties of sequence-specific DNA probes.

The Eclipse quencher from ELITechGroup solves most of the problems inherent in the synthesis of molecular beacon and FRET probes. The Eclipse molecule is highly stable and can be used safely in all common oligo deprotection schemes.
