PEI-g-PEG-SH

Catalog:CDN1302

Unit Size:100 mg

Specifications

Common Use	PEI-g-PEG-SH is a graft copolymer of branched PEI (bPEI), which is modified with multiple SH-PEGs of indicated MW. Copolymers of cationic poly(ethyleneimine) grafted with thiol-polyethylene glycol (PEG) (PEI-g-PEG-SH) are extremely well-studied compounds that markedly improve the in vitro and in vivo delivery of oligonucleotides (AOs) to cells and tissues. PEI-g-PEG-SH can be used to prepare cationic-nanoparticles for targete gene/AOS delivery. Thiol can y reacts with maleimide and novel metal surface including gold, silver, etc
