ATTO 580Q is a novel fluorescence quencher (energy acceptor in FRET process). Characteristic features of the label are strong absorption and high thermal and photo-stability. The dye is moderately hydrophilic. ATTO 580Q is a cationic dye. After coupling to a substrate the dye carries a net electrical charge of +1. ATTO 580Q consists of six isomers with practically identical absorption.
- High thermal and photo-stability
- Moderately hydrophilic
- Cationic dye related to rhodamines
- Supplied as mixture of six isomers
