ICG amine

Ex: 780 nm. Em: 800 nm. Soluble in: DMSO. Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, and liver blood flow, and for ophthalmic angiography. It has a peak spectral absorption close to 800 nm. These infrared frequencies penetrate retinal layers, allowing ICG angiography to image deeper patterns of circulation than fluorescein angiography. This ICG amine can be used to modify the molecules that contain a carbonyl group (such as an aldehyde or a carboxy group).
