sulfo cy5.5 ethylenediamine

Sulfo-Cyanine5.5 is a water soluble cyanine dye for far red NIR applications such as in vivo imaging. The dye possesses four sulfonate groups that render it highly hydrophilic and water soluble. As well as other cyanines, sulfo-Cyanine5.5 has an outstanding extinction coefficient that makes it a bright fluorescent label for the far red region.
