Sulfo-Cyanine7.5 carboxylic acid
产品介绍
Sulfo-Cyanine7.5 is a water soluble, near infrared fluorescent dye. The structure of the dye is similar to indocyanine green (ICG), but it contains a rigid trimethine linker increasing its fluorescence uantum yield.
This fluorophore is useful for near infrared imaging. Sulfo-Cyanine7.5 carboxylic acid contains a free carboxy group.
