Optical properties

  • λ abs = 582 nm
  • ε max = 1.2×105 M -1 cm -1
  • CF 260 = ε 260 /ε max = 0.29
  • CF 2800 = ε 280 /ε max = 0.12

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.
