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)
