Description

  • Bright, water-soluble, amine-reactive label containing one NHS-ester group.

 

Advantages

  • Suited for excitation with 635, 640, and 650-nm diode lasers
  • Lower quenching tendency at high dye-to-protein ratios compared to other labels e.g. Cy5™
  • Well-suited for confocal and 2-photon imaging and fluorescence polarization measurements
  • High 2PACS
  • Considerably higher photostability compared to fluorescein or other cyanine dyes (Cy5.5)
  • High chemical stability against oxidation with peroxides or other oxygen species
  • Longer fluorescence lifetime (τ = 1.7 ns) compared to Cy5 (τ = 1.0 ns) or Alexa 680 (τ = 1.2 ns)
  • Higher brightness (Φ.ε = 99,000) compared to Alexa 680 (Φ.ε = 68,800) or Alexa 660 (Φ.ε  = 48,800)
