Product Introduction
QXY7 has a broad and intense absorption at ~550 nm maxima with no detectable fluorescence, making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications paring with Cy3, TAMRA, Alexa Fluor 555 and iFluor 647 or other spectrally similar fluorescent dyes. QXY7 NHS ester is quite stable and readily reacts with amino-containing molecules such as amino-modified oligos, proteins and peptides.
