Figure 1. Evaluation of brain delivery of Evans Blue (EB) by various peptides (A) and by different concentration of peptide K16ApoE (B).
67.5 picomoles of each of the peptides (K16, ApoE and K16ApoE) was either injected first followed in 10 min by injection of EB (40 ul of a 2% solution) or the dye and the peptides were mixed together and then injected. Mice were perfused with saline 2 h after injection and then brains were collected for visualization.
