Polyethylenimine (branched) (30% in water) [9002-98-6]

Polyethylenimine (branched) (30% in water) is a organic macromolecule with high cationic-charge-density potential. Polyethylenimine (branched) (30% in water) can ensnare DNA as well as attach to cell membrane. Polyethylenimine (branched) (30% in water) also retains a substantial buffering capacity at virtually any pH. Polyethylenimine (branched) (30% in water) is widely used as transfection reagent^[1].

Polyethylenimine branched (ranged PEI/DNA ratio, 24 h) reaches maximal transfection efficiency at 9-13.5 equivalents of PEI nitrogen per DNA phosphate and does not affect cell metabolism in 3T3 cells. ^[1].
