Description

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)
