描述

Branched Polyethylenimine, Mw 2,000,000, 25% w/v aq. soln. (bPEI 2000000 25% soln.) is highly branched polyamine with high cationic charge density. bPEI 2000000 contains primary, secondary, and tertiary amine groups with pH 8.

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.
