ATTO 575Q 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 575Q is a cationic dye. Contrary to ATTO 580Q, ATTO 575Q is supplied as single isomer.
After coupling to a substrate the dye carries a net electrical charge of +1.
- High thermal and photo-stability
- Moderately hydrophilic
- Cationic dye related to rhodamines
- Single isomer
