8-Arm-PEG-Mal

8-Arm maleimide-functionalized discrete poly(ethylene glycol) (8-Arm-PEG-MAL) is an 8-arm precision PEG derivative. The PEG arms present terminal maleimide groups. 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 multiarm structure provides attachment sites for multivalent ligand display or network construction. Arm number, chain length, and functional-group equivalents can be varied to compare crosslink spacing and molecular presentation. In this series, n denotes the number of ethylene glycol repeat units in each PEG arm.

Applications:

Eight-arm PEG multivalent conjugation;
Branched PEG construction;
Crosslinking and site-density studies;
Cysteine-site modification;
Thiol-selective bioconjugation.

Customization available.
