Sulfo-Cyanine7 carboxylic acid is non-reactive water soluble near infrared dye.

The reagent is useful as a fluorescent marker in NIR range when attachment to other molecules is not desired. It has high hydrophilicity and aqueous solubility, improved quantum yield in NIR range, and very high molar extinction coefficient.

This reagent contains free carboxylic acid function. Pre-activated activated ester - sulfo-Cyanine7 NHS ester is also available.
