Quasar 570 is an indocarbocyanine which fluoresces in the yellow-orange region of the visible spectrum. This compound is a direct replacement for Cy3 dye. Quasar 570 amidite is used for the 5' labeling of fluorogenic probes used in 5' nuclease assays, Molecular Beacons, Scorpions primers, and other detection assays. BHQ®-2 dye will quench the Quasar 570 moiety.
For internal labeling we recommend the use of Cy3-NHS that is conjugated post synthesis using an amino group. BR>
