General description

Poly(ethylene glycol) (PEG), a linear polyether of ethylene glycol (ethane-1,2-diol), is soluble in water, benzene, ethanol, acetonitrile, and dichloromethane. However, it is insoluble in diethyl ether and hexane. This non-ionic polymer can exist in the monomer and aqueous phases.

Application

Poly(ethylene glycol) has been used:

  • in cryopreservation of cell-laden multi-assay platforms (MAPs)
  • as a macromolecular crowder to study its effects on fluorescein isothiocyanate (FITC)-conjugated type-I collagen
  • as a model surfactant in surfactant formulations to evaluate the interfacial aggregation of antibody formulations in response to interfacial stress

Biochem/physiol Actions

Poly(ethylene glycol) (PEG) is used in several applications including medicine. This polymer occurs as a preservative and is used in biomedical applications like drug delivery systems, biosensing, and tissue engineering. PEG is also used in cosmetic ointments and creams. It is used as a binding and dispersing agent in chemical and other industries.

Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.

Aldrich Products

  • For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').

  • For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').

  • For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.

Not Finding What You Are Looking For?

In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
