A series of nano-sized dendritic α,ε-poly(L-lysine)s (DPL) were synthesized by the solid-phase peptide synthesis method, using a core ε-peptide structure consisting of eight lysine residues. Surface amines of dendritic α,ε-poly(L-lysine) were characterized by comparing the retention times of a reverse phase HPLC with the electrophoretic mobilities of capillary zone electrophoresis (CZE) and non-denatured polyacrylamide gel electrophoresis (PAGE). The elution times of α,ε-poly(L-lysine) in HPLC were well correlated with the electrophoretic mobilities of CZE and PAGE. The separation was dependent on size, shape of molecule and the number of surface amine. The α,ε-poly(L-lysine) formed a complex with nucleic acids at various charge ratios and the degree of complex formation was size- and structure-dependent. Atomic force microscopy of the complex visualized the size and morphology of α,ε-poly(L-lysine)/DNA complex as a nano-sized spherical shape. The small size in complex formation provides a promise for in vivo therapeutic application of dendritic α,ε-poly(L-lysine)s or their derivatives in the delivery of gene or oligonucleotide.

Prion Infectivity

Results of experiments by two prion research groups support the view that prions are protein-based, infectious entities not made up of transmissible nucleic acids. In these experiments, infectivity with purified prion protein was demonstrated
