ICG PEG DBCO (MW 5000)

ICG PEG DBCO (MW 5000) is a fluorescent probe that incorporates the Indocyanine green (ICG) dye. This compound features a clickable DBCO functional group and a PEG chain, enabling it to undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing azide groups, with excitation/emission wavelengths at 785/813 nm.
