Ortho-pyridyl disulfide (OPSS) and fluorescein functionalized polyethylene glycol (OPSS PEG FITC) is a thiol (-SH) group reactive and fluorescent 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. Meanwhile, fluorescein gives strong green fluorescent signal that can be easily detected.
