Biological Activity

Polyethylenimine (branched) is a hydrophilic cationic polymer that functions as an efficient non-viral gene vector for nucleic acid delivery. It condenses negatively charged DNA or RNA into nanoscale polyplexes, facilitating cellular uptake via endocytosis and promoting endosomal escape through the proton-sponge effect to enhance gene transfer efficiency and intracellular transgene expression across various cell types.
