Brain accumulation and biodistribution of pDNA polyplexes in mice. (A) Brain accumulation of radiolabeled BH and ApoE-vectorized polyplexes (3H-pLPEI) at different peptide contents (%wt); 1 h after i.v. injection in mice (n = 3). (B) Bioimaging of BH peptide-vectorized and non-vectorized pLPEI-polyplexes of rhodamine-labeled pDNA. Pictures were taken 1 h-post-injection in the tail vein of Balb/c mice using Xenogen IVIS-200 bioimager, and fluorescence intensities were converted by the instrument software.
