General description

Polyethylene glycol (PEG) is a hydrophilic polymer. It can be easily synthesized by the anionic ring opening polymerization of ethylene oxide, into a range molecular weights and variety of end groups. When crosslinked into networks PEG can have high water content, forming “hydrogels PEG is a suitable material for biological applications because it does not trigger an immune response.

Application

Polyethylene glycol (PEG) platelets were used:
  • in PEG-directed gene delivery of protoplast transfection and incubation[1]
  • to prepare extraction for measuring cytosolic phosphoenolpyruvate carboxykinase (PEPCK) from plant tissues
  • as DNA transformation agent in a study of transient gene expression of plant protoplasts, derived from rice leaf sheaths.[2]
  • in preparing isothermal assembly buffer and TSS broth preparation for unique nucleotide sequence (UNS)-guided assembly of repetitive DNA parts[3]
  • in transformation of DNA into log-phase cells of the budding yeast Saccharomyces cerevisiae.[4]
  • as DNA transformation reagent[5]

Other Notes

Polymer networks with grafted cell adhesion peptides for highly biospecific cell adhesive substrates[6]
