Description

  • Extremely bright, water-soluble fluorescent probe for imaging applications.

 

Advantages

  • Suited for excitation with 630–650-nm light sources
  • Large Stokes’ shift of ~46 nm (about twice that of Cy5 or Alexa 647).
  • Considerably higher photostability compared to fluorescein or other cyanine dyes (Cy5 or Alexa dyes)
  • High chemical stability against oxidation with peroxides or other oxygen species
  • Several times longer fluorescence lifetime (τ ~ 3 ns ) compared to Cy5 or Alexa 647 (τ ~ 1 ns)
  • Extremely bright and photostable fluorescent probe for the 647-nm Kr-ion laser line
  • Very high 2-photon excitation action cross-section (>3,000 GM)
