cPEG-PEG-Mal

Cyclic PEG with PEG arm, Mal

Maleimide-terminated PEG arm on a cyclic poly(ethylene glycol) scaffold (cPEG-PEG-MAL) is a cyclic-topology derivative bearing a pendant PEG arm. The specified conjugation or functional groups are located on the pendant segment. Discrete chain lengths with different degrees of polymerization are available. The maleimide can add to cysteine thiols or other thiolated modules, providing a handle for conjugation at thiol sites. The cyclic scaffold retains its topological features, while the pendant arm provides conjugation and presentation functions. This allows the effects of ring structure and pendant-chain length on molecular conjugation to be distinguished.

Applications:

Cyclic topology effect studies;
Molecular conjugation through pendant arms;
Cysteine-site modification;
Thiol-selective bioconjugation.

Customization available.
