||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.
||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.
