Application
Poly(ethylene glycol) was used as hydrophilic carriers for characterizing the sirolimus solid dispersion nanoparticles.
Biochem/physiol Actions
Polyethylene glycol (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.

Previous studies on the refolding of recombinant bovine carbonic anhydrase B (CAB) indicated that polyethylene glycol (PEG) significantly enhanced the recovery of active protein by reducing aggregation. To further test the ability of PEG to enhance refolding, three recombinant human

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

The pericellular matrix (PCM) surrounding chondrocytes is thought to play an important role in transmitting biochemical and biomechanical signals to the cells, which regulates many cellular functions including tissue homeostasis. To better understand chondrocytes interactions with their PCM, three-dimensional poly(ethylene

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
