sulfo-Cyanine7 carboxylic acid is a non-reactive water-soluble near-infrared dye.
The reagent is useful as a fluorescent marker in the NIR range when attachment to other molecules is not desired. It has high hydrophilicity and aqueous solubility, improved quantum yield in the NIR range, and a very high molar extinction coefficient.
This reagent contains free carboxylic acid function. Pre-activated activated ester - sulfo-Cyanine7 NHS ester is also available.
