RB-PEG-N3 (MW 600)

RB-PEG-N3 (MW 600) (Rhodamine B-PEG-N3 (MW 600) ) is a fluorescent dye composed of Rhodamine B , PEG and azide group (N3). RB-PEG-N3 (MW 600) is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups (Ex/Em = 546/610 nm).
