描述

Branched Polyethylenimine, Mw 750,000, 33% w/v aq. soln. (bPEI 750000 33% soln.) is highly branched polyamine with high cationic charge density. bPEI 750000 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.
