Polyethylenimine, branched (MW 2,000) - 100g

Branched Polyethyleneimine, Mw 2000 (bPEI 2000) is branched liquid water soluble polyamine with a high cationic charge density that readily binds anionic substrates. It can be used in the formulation of nanocarriers, such as PEI coated graphene oxide nanoparticles or PEI coated mesoporous silica nanocarriers, for a combination of nucleic acid and drug delivery.
