| Branched PEI-g-PEG | PEI-g-PEG is a graft copolymer of branched PEI (bPEI), which is modified with multiple PEGs of indicated MW. The PEG to PEI ratio is the average number of PEGs per PEI. Uses: Copolymers of cationic poly(ethyleneimine) wight grafted with polyethylene glycol (peg) (pei-g-peg) are extremely well-studied compounds that markedly improve the in vitro and in vivo delivery of oligonucleotides (aos) to cells and tissues. by varying the mw of pei, as well as the nature of peg shielding, peg-pei-ao nanoparticulates can be prepared with a dynamic range of size, surface charge, and stability. each of these properties in-turn influences the transfection capacity of the peg-pei-ao polyplexes. in addition, peg-pei copolymers are readily functionalized for enhanced efficacy and specificity of cellular and tissue targeting. Group: Hydrophilic polymers. Alternative Names: PEI-PEG, Branched polyethylenimine-graft-poly(ethylene glycol), PEI-g-PEG. Molecular formula: PEG Mn 550.
