Branched Polyethylenimine, Mw 600 (bPEI 600) is highly branched liquid water soluble polyamine with high cationic charge density. bPEI 600 contains primary, secondary, and tertiary amine groups in approximately 25/50/25 ratio.Industrially, branched polyethylenimine (bPEI) have extensive applications as an auxiliary agent intensifying manufacturing processes and improving quality of the final products. They are widely used in: paper-making, water treatment, detergents, adhesives, and cosmetics. In research, they are extensively investigated as non-viral vector carriers.Resin Content (wt%): ≥ 99%
