QSY-9-succinimidyl ester is a nonfluorescent acceptor molecule that features a terminal NHS ester group. It exhibits a broad and intense quenching capability in the 500-600 nm range, making it ideal for use in fluorescence resonance energy transfer (FRET) applications alongside fluorescent dyes emitting in this spectrum. The reactive NHS ester effectively labels primary amines (-NH2) on proteins, amine-modified oligonucleotides, and other amine-bearing compounds, facilitating diverse biochemical analyses and detection methodologies.
