ICG PEG biotin (MW 2000)

ICG PEG biotin (MW 2000) is a fluorescent dye composed of Indocyanine green (ICG) , PEG and biotin. Indocyanine green provides it with fluorescent labeling function, PEG enhances its biocompatibility and stability, and biotin can bind to target molecules containing streptavidin to achieve targeted imaging or targeted delivery (Ex/Em = 785/813 nm).
