Polyethyleneimine (PEI), also known as polyethyleneimine, is a water-soluble polymer. Colorless or yellowish viscous liquid, hygroscopic, soluble in water, ethanol, insoluble in benzene.
PEG-PEI, a copolymer of cationic poly (ethylene imide) (PEI) and polyethylene glycol (PEG), is a well-studied compound that significantly improves the delivery of oligonucleotides and nucleic acids (DNA, siRNA) in vitro and in vivo. By varying the MW of PEI and PEG, PEG-PEI drug conjugates, polymers, or nanoparticles with dynamic range of size, surface charge, and stability can be prepared, all of which are important for transfection efficiency.
PEI-PEG-DSPE, polyethylenimine-PEGyl-phospholipid is an AB block copolymer with phospholipids at the end of PEG that can be used in drug delivery systems. DSPE, 1, 2-distearoyl-SN-glycerol-3-phosphate ethanolamine is a synthetic phospholipid that can be used as a membrane material with solubility and is suitable for the development of liposomes and phospholipid complexes.
