RB-PEG-N3 (MW 1000)

RB-PEG-N3 (MW 1000) (Rhodamine B-PEG-N3 (MW 1000) ) is a fluorescent dye composed of Rhodamine B, PEG, and an azide group (N3) . As a click chemistry reagent, it features the azide group capable of undergoing copper-catalyzed azide-alkyne cycloaddition (CuAAC) with alkyne-containing molecules. Additionally, it can participate in strain-promoted azide-alkyne cycloaddition (SPAAC) with molecules containing DBCO or BCN groups, with excitation and emission at 546/610 nm.
