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.

This is an amine-containing fluorescent dye. The amine group is separated from the fluorophore by a relatively long linker that facilitates conjugation. The aliphatic primary amine group can be coupled with various electrophiles (activated esters, epoxides, etc), and also be used in enzymatic transamination labeling.

IUPAC name:

(E)-4-[(2E,4E)-5-{5-[6-(6-Aminohexylamino)-6-oxohexyl]-3,3-dimethyl-10,12-bis(oxysulfonyl)-5-azatricyclo[7.4.0.02,6]trideca-1,4,6,8,10,12-hexaen-4-yl}-2,4-pentadienylidene]-3,3-dimethyl-5-methyl-5-azatricyclo[7.4.0.02,6]trideca-1,6,8,10,12-pentaene-10,12-disulfonic acid dipotassium salt
