Bis-(N,N'-PEG4-NHS ester)-Cy5 Usage And Synthesis

Description

Bis-(N,N'-NHS-PEG4)-Cy5 is a cyanine labeled PEG linker with excitation/emmission maximum 649/667 nm containing a NHS ester group, which is an amine reactive group. Hydophilic PEG spacer increases solubility in aqueous media. This reagent can be utilized to produce Cyanine-labeled biomolecules for subsequent use such as in vivo research, and drug design related experiments.

Uses

Bis-(N,N'-PEG4-NHS ester)-Cy5 is an alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTACs[1].

IC 50

Alkyl/ether
