Application

Poly (ethylene glycol) was used for metabolic labeling and immunoprecipitation. It is suitable for radioimmunoassay.

Biochem/physiol Actions

Polyethylene glycol (PEG) also referred to as as Macrogol 3,000 or PEG is a condensation polymer of ethylene oxide and water. It enhances the refolding of extracted proteins. This enables characterization of crystallized proteins.

Preparation Note

Poly(ethylene glycol) dissolves in many organic solvents and is readily soluble in aromatic hydrocarbons. It also slightly dissolves in aliphatic hydrocarbons.

Monoclonal antibodies were produced following immunization of mice with either [Leu5]enkephalin-bovine serum albumin or [Met5]enkephalin-keyhold limpet hemocyanin conjugates. Two monoclonal antibodies coded NOC1 and NOC2, respectively, were derived. These monoclonal antibodies did not discriminate between Leu- and Met-enkephalin in either

Polyethylene glycol (PEG) inhibited aggregation during refolding of bovine carbonic anhydrase B (CAB) through the formation of a nonassociating PEG-intermediate complex. Stoichiometric concentrations of PEG were required for complete recovery of active protein during refolding at aggregating conditions. For example

Ultrasound has potential as a non-destructive analytical technique to provide real-time online assessments of matrix evolution in cell-hydrogel constructs used in tissue engineering. In these studies, chondrocytes were encapsulated in poly(ethylene glycol) hydrogels, and gel degradation was manipulated to provide
