Polyethylene Glycols (PEG)
Reagents for Pegylation
PEGs possess a variety of properties pertinent to biomedical and biotechnical applications.
A summary of some properties of interest is given here:

• Soluble in water, toluene, methylene chloride, many organic solvents.
• Insoluble in ethyl ether, hexane, ethylene glycol.
• Insoluble in water at elevated temperature.
• Solubility and partitioning controlled by making derivatives.
• Forms complexes with metal cations.
• Highly mobile; large exclusion volume in water.
• Can be used to precipitate proteins and nucleic acids.
• Forms two-phase systems with aqueous solutions of other polymers.
• Nontoxic; FDA approved for internal consumption.
• Hospitable to biological materials.
• Causes cell fusion (in high concentration).
• Weakly immunogenic.
