Description Polyethylenimine (linear) is a versatile cationic polymer with a high transfection efficiency. It is used as a gene delivery reagent. It is a non-lipid polycation that can be used to transfect oligonucleotides and plasmid into cells in vitro and in vivo.

Application Branched polyethyleneimine (PEI) is widely used in many s due to its polycationic character. Unlike its linear equivalent, branched PEI contains primary, secondary, and tertiary amines. Primarily utilized in industrial s, high molecular weight PEI has been used as a flocculating agent, textile coating, adhesion promoter, enzyme carrier, and as a material for CO2 capture.
Polyethylenimine, branched (PEI) is a hydrophilic polymer and a gene carrier, which can be conjugated with dextran to enhance the stability of polycationic vectors. It is also used in the preparation of cationic poly(lactic-co-glycolic acid) (PLGA) nanoparticles for potential usage in gene therapy. PEI can also be grafted on polyacrylonitrile (PAN) fiber membrane for the removal of hexavalent chromium (VI) from wastewater.

Features And Benefits They can interact with or be dissolved by water or other polar substances.
