General description
Polyethylenimine (PEI) is polymer with positive charge density. It has various uses like in water purification, paper industry, to remove nucleic acids from protein solutions and many more. This polymer was first used in DNA and oligonucleotides delivery. It may also be used as transfection reagent. Silica gels are chemically modified with PEI to be used as sorbent. PEI stabilizes high surface area solid to adsorb CO2.
Application
Ion-exchange resin
Polyethylenimine may be used in separation medium for TLC, paper chromatography and LPLC. Polyethylenimine on silica gel may be used for thin layer chromatography.
