QSY 9® Quencher Oligonucleotide Modification
Bio-Synthesis offers QSY® 9 quencher modified oligonucleotide. QSY9 has a broad and intense quenching range of 500-600 nm. It has no fluorescence which making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications.
- Nonfluorescent quencher
- Spectrally similar to QSY 7, but with enhanced water solubility
- Efficient energy-transfer acceptor from green and orange fluorophores
QSY9 Quencher can be incorporated at any position within an Oligonucleotide. A primary amine modified oligonucleotide is used to covalently attach with dye via NHS conjugation chemistry; other cross-linking chemistries are also available depending on particular project specifications. Dual HPLC purification is highly recommended.

-20°C To -70°C
Oligonucleotides are stable in solution at 4°C for up to 2 weeks. Properly reconstituted material stored at -20°C should be stable for at least 6 months. Dried DNA (when kept at -20°C) in a nuclease-free environment should be stable for years.
