Extremely bright, water-soluble, amine-reactive squaraine-rotaxane label containing one NHS-ester group. The ideal label for proteins and other amino-modified biomolecules, including oligonucleotides.
Advantages
Perfectly suited for excitation with the 635-nm, 650-nm, 670-nm, and 680-nm LEDs and diode lasers
Low quenching tendency at high dye-to-protein ratios compared to other labels, e.g., Cy5.5™
Considerably higher photostability compared to other cyanine dyes (Cy5.5 or Alexa 680)
High chemical stability against oxidation with peroxides or other oxygen species
