COA of QCY 7 NHS
Description:
QCY 7 NHS and QSY 7 NHS refer to the same molecule. QCY 7 features a broad and intense absorption with a peak at around 550 nanometers and has no detectable fluorescence. These characteristics make it highly useful as an acceptor in Fluorescence Resonance Energy Transfer (FRET) applications when paired with fluorescent dyes such as Cy3, TAMRA, Alexa Fluor 555, iFluor 647, or other dyes with similar spectra.
