sulfo-Cyanine3 in Fluorophores

Absorption max 548 nm Emission max 563 nm Fluorophore chart

sulfo-Cyanine3 is a water soluble and hydrophilic version of Cyanine3 fluorophore. It is an analog of Cy3® dye.

The dye possesses very high extinction coefficient and good quantum yield, outstanding photostability, and high hydrophilicity due to the presence of two sulfo groups. It is negatively charged at physiological pH values.

A number of reactive derivatives is available from our catalog. A non-sulfonated version of this dye is Cyanine3.
