Description:

Ortho-pyridyl disulfide (OPSS) functionalized polyethylene glycol (OPSS PEG) is a thiol (-SH) group reactive PEG derivative that can be used to modify biomolecules or other materials via their available thiol groups. Ortho-pyridyl disulfide reacts with thiol group to form a stable disulfide bond while a thiol pyridyl group is released.

Physical Properties:

  • Off-white/white solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

Storage Conditions:

  • Store at -20 0C, dessiccated. Avoid frequent thaw and freeze.
