Application:	Polyethylene glycol (PEG) platelets were used: • in PEG-directed gene delivery of protoplast transfection and incubation • 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. • in preparing isothermal assembly buffer and TSS broth preparation for unique nucleotide sequence (UNS)-guided assembly of repetitive DNA parts • in transformation of DNA into log-phase cells of the budding yeast Saccharomyces cerevisiae. • as DNA transformation reagent
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.
