IR-820

Description: IR-820 (New Indocyanine Green) is a near-infrared dye with improved stability, good color rendering, and excellent fluorescence penetration. It serves as an infrared blood pool contrast agent for detecting and quantifying diseased tissue in live animals, with maximal excitation (Ex) and emission (Em) of 710 and 820 nm, respectively.
