Quasar 570 is identical to Cy3 and Quasar 670 is identical to Cy5. Cy3 and Cy5 named fluorophores are available for 5', 3', Internal and NHS forms for post synthesis conjugation. Please see related fluorophores listed above. Click here for list of fluorophores.

Quasar 570 is an indocarbocyanine which fluoresces in the yellow-orange region of the visible spectrum. This fluorophore 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>
