    We developed novel gene vectors composed of dendrigraft poly-L-lysine (DGL). The transgene expression efficiency of the pDNA/DGL complexes (DGL complexes) was markedly higher than that of the control pDNA/poly-L-lysine complex. However, the DGL complexes caused cytotoxicity and erythrocyte agglutination at high doses.Author: Yukinobu Kodama, Tadahiro Nakamura, Tomoaki Kurosaki, Kanoko Egashira, Toyoharu Mine, Hiroo Nakagawa...

    While the poly-L-lysine (PLL) precursor amino acid occurs naturally, the poly-D-lysine (PDL) precursor is an artificial product. The latter is therefore thought to be resistant to enzymatic degradation and so may prolong cell adherence. Polylysine in drug deliveryChemical formula: (C₆H₁₂N₂O)ₙ

    Abstract. Nonviral gene delivery has great potential for replacement of recombinant protein therapy. In many cases, gene therapies would be a considerable improvement over existing therapies because of putative advantages in dosing schedule, patient compliance, toxicity, immunogenicity, and cost.Author: Charles P.
