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.

Our granulates are ideally suited for further processing into extrusion and injection moulded parts. The consistent quality of our production enables the use in the most diverse areas of application.
The basis for our granulates are different polymers, which differ in their physical properties. By adding additives we can produce individual compounds and recompounds for our customers;
