ICG PEG biotin (MW 2000)

ICG PEG biotin (MW 2000) is a fluorescent dye comprised of Indocyanine Green (ICG), PEG, and biotin. The ICG provides fluorescence labeling capability, PEG enhances biocompatibility and stability, and biotin allows binding to target molecules containing streptavidin, enabling targeted imaging or delivery (Ex/Em = 785/813 nm) .
