PEG-PEI Polyethylenimine – Copolymers of cationic poly(ethylene imine) and PEG improve in vitro and in vivo delivery of oligonucleotides and nucleic acids (DNA, siRNA, mRNA), and improve transfection efficiency. We offer block copolymer PEG-PEI, PEI-PEG-PEI and graft copolymer of PEG grafted to linear or branched PEI.
