N-(m-PEG4)-N'-(amino-PEG3)-Cy5 Usage And Synthesis

Description

N-(m-PEG4)-N'-(amino-PEG3)-Cy5 TFA salt is a PEG linker containing a cyanine dye with excitation/emmission maximum 649/667 nm and a free amine group, which will be reactive with cabroxylic acid, activated NHS ester, carbonyl (ketone, aldehyde) etc. The hydophilic PEG spacer increases solubility in aqueous media.

Uses

N-(m-PEG4)-N'-(amino-PEG3)-Cy5 is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
