sulfo-cy-5.5 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.

Sulfo-Cyanine7 is an improved analog of Cy7 fluorophore with quantum yield improved by 20%, and higher photostability. This fluorescent dye is especially useful for NIR imaging.

Sulfo-Cyanine 3 is an alternative dye primarily used for labeling peptides and oligos in replacing Cy3 that was originally developed by GE Healthcare.

Sulfo-CY-5.5 NHS ester (Sulfo-Cyanine5.5 NHS ester) tripotassium is a sulfonated far-red Cyanine5.5 fluorophore ester that reacts with amines. It is commonly used to label antibodies, proteins, and other molecules for in vivo NIR imaging [1].

Sulfo-Cyanine5 is an analog of Cy5, a very popular fluorophore, therefore this reagent is compatible to a wide range of standard fluorescent instrumentation such as imagers, plate readers, and microscopes.
