N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 is a PEG linker containing cyanine dye with excitation/emmission maximum 555/570 nm and an alkyne group, which enables copper-catalyzed Click Chemistry. The hydophilic PEG spacer increases solubility in aqueous media.
N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-methyl-N'-methyl-O-(m-PEG4)-O'-(propargyl-PEG4)-Cy3 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
