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.
