Iodoacetyl PEG Acid, IA-PEG-COOH
Iodoacetyl (IA) functionalized polyethylene glycol (IA PEG) is a thiol (-SH) group reactive PEG derivative that can be used to modify biomolecules or other materials via their available thiol groups. Iodine group can be easily replaced by thiol group to form a stable carbon thiol bond.
