AbstractProtein transduction domains (PTD) have been identified to have the capacity to facilitate molecular cargo to translocate through cell membrane. This study aims to utilize the cell membrane penetrating ability of octaarginine oligopeptide, a simplified prototype of the PTD, to enhance the transfection efficiency of chitosan. Octaarginine-modified chitosan (R 8-CS) was synthesized as a gene transfer carrier by carbodiimide chemistry. The structure and composition of R 8-CSs were characterized using FTIR and 1H NMR. Agarose gel electrophoresis assay showed that R 8-CS could efficiently condense the DNA. The particle size of R 8-CS/DNA complexes were determined to be around 100-200 nm. The nanoparticle complexes exhibited a spherical and compact morphology. R 8-CS demonstrated higher transfection activity and lower cytotoxicity as compared to the unmodified chitosan and also showed good serum resistance. © Springer Science+Business Media B.V. 2010.
