4-Arm-PEG-OPSS

4-Arm pyridyl disulfide-functionalized discrete poly(ethylene glycol) (4-Arm-PEG-OPSS) is a 4-arm precision PEG derivative. The PEG arms present terminal pyridyl disulfide groups. Discrete chain lengths with different degrees of polymerization are available. The pyridyl disulfide provides a reactive end for thiol exchange. The resulting linkage can be used in studies of reduction-responsive structures. 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:

Four-arm PEG multivalent conjugation;
Branched PEG construction;
Crosslinking and site-density studies;
Disulfide conjugation;
Reducible crosslinked networks.

Customization available.
