Description

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

 

Advantages

  • Perfectly suited for excitation with 635, 640, and 650-nm diode lasers
  • 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 (t ~ 3 ns ) compared to Cy5 or Alexa 647 (t ~ 1 ns)
  • Extremely bright and photostable fluorescent probe for the 647-nm Kr-ion laser line
  • Very high 2-photon excitation action cross-section (>3000 GM)
