ATTO 540Q 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 540Q is a cationic dye.
After coupling to a substrate the dye carries a net electrical charge of +1. As supplied ATTO 540Q consists of a mixture of two isomers with practically identical absorption.
