General description

Polyethylenimine(PEI) is a synthetic cationic polymerwith high charge density and chain flexibility. It is the most widelyinvestigated cationic polymer for non-viral delivery of nucleic acids. LinearPEI can be an effective carrier for a wide range of gene medicine including DNAplasmids, small interfering RNAs, and mRNAs. It protects the DNA from theacidic environment and ensures the release of DNA to the cytoplasm.
