Description

Sulfo-Cyanine7 carboxylic acid is non-reactive water soluble near infrared dye._x000D_ _x000D_ 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.

Uses

Sulfo-Cyanine7 carboxylic acid is a highly hydrophilic and water-soluble near-infrared dye. It improves quantum yield in the near-infrared range and has a very high molar extinction coefficient.
