Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1
. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo
than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation.
4-Arm PEG-Thiol is a multiarm PEG derivative with thiol groups at each terminal of the four arms connected to one pentaerythritol core.
