DusQ2 CPG 1000 This modified support is intended for the synthesis of oligonucleotides with DusQ2 quencher at the 3’ end. Pore size of 1000 Å is recommended for the synthesis of oligonucleotides of up to 120 bases in length.DusQ2 is a fluorescence quencher with absorption within the range of 560 to 670 nm. It is ideal for effective FRET quenching of fluorophores with emission in this range. The quencher is also used in hybridization probes with static and combined quenching. Its quenching effectiveness does not depend very much on overlapping of fluorophore and quencher spectra, thus allowing for effective quenching of the broad spectrum of fluorophores, including those with emission in the red and far-red part of the spectrum. Thus, DusQ2 can be used with such fluorophores (including but not limited to) as Cyanine3, TAMRA, ROX, Cyanine3.5, Quasar® 570, Pulsar® 650, Cyanine5, Quasar 670, Cyanine5.5, and Quasar 705.
