Crosslinked linear polyethylenimine enhances delivery of DNA to the cytoplasm.
Crosslinked polyethylenimines (PEIs) have been frequently examined over the past decade since they can maintain the transfection efficiency of commercially available, 25k branched PEI, but exhibit less cytotoxicity. The argument is often made that the degradability of such polymers, generally synthesized with either disulfide or hydrolytically degradable crosslinkers, is critical to the high ef...
متن کاملOcular gene delivery systems using ternary complexes of plasmid DNA, polyethylenimine, and anionic polymers.
In this experiment, we developed anionic ternary complexes for effective and safe ocular gene delivery. Ternary complexes were constructed by coating plasmid DNA (pDNA)/polyethylenimine (PEI) complex with anionic polymers such as γ-polyglutamic acid (γ-PGA) and chondroitin sulfate (CS). The cationic pDNA/PEI complex showed high gene expression on the human retinal pigment epithelial cell line, ...
متن کاملTranscription of plasmid DNA: influence of plasmid DNA/polyethylenimine complex formation.
Polyethylenimine (PEI) is one of the most potent non-viral vectors. We have developed a lactosylated PEI (Lac-PEI) to enhance cell-specific transfection and have shown that Lac-PEI is more efficient than unsubstituted PEI for gene transfer into immortalized cystic fibrosis airway epithelial SigmaCFTE29o-cells. As both intact PEI/plasmid and Lac-PEI/plasmid complexes are found in the cell nucleu...
متن کاملcomparison of two delivery systems efficiency by using polyethylenimine (pei) for plasmid hpv16e7 dna transfection into cos-7 cells
objective: dna vaccines have been widely used to develop immunity against various pathogens including parasites and viruses. the potential of dna vaccine to induce an effective immune response is related to the expression levels of the encoded protein in eukaryotic cells. therefore, optimization of plasmid dna delivery system is a major concern in protein expression in order to make an efficien...
متن کاملPolyethylenimine-mediated gene delivery to the lung and therapeutic applications
Nonviral gene delivery is now considered a promising alternative to viral vectors. Among nonviral gene delivery agents, polyethylenimine (PEI) has emerged as a potent candidate for gene delivery to the lung. PEI has some advantages over other polycations in that it combines strong DNA compaction capacity with an intrinsic endosomolytic activity. However, intracellular (mainly the nuclear membra...
