Optical properties

  • λ abs = 615 nm
  • ε max = 1.15×105 M -1 cm -1
  • CF 260 = ε 260max = 0.35
  • CF 2800 = ε 280max = 0.60

ATTO 612Q 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 612Q is a cationic dye.

After coupling to a substrate the dye carries a net electrical charge of +1. As supplied ATTO 612Q consists of a mixture of two isomers with practically identical absorption.
