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.
