Calcium phosphate nanoparticles provide safe and easily manufactured vaccine adjuvant and delivery system for DNA vaccines. In the present study FMDV O P1-3CD DNA vaccine was encapsulated in calcium phosphate nanoparticles of size 50-100 nm diameters. The maximum loading and entrapment efficiency of nanoparticles were studied by spectrophotometer, as well as agarose gel electrophoresis. In vitro transfection efficiency of these calcium phosphate nanoparticles was found to be as good as commercial transfecting reagent lipofectamine. In vivo analysis of the calcium phosphate nanoparticle P1-3CD (CaPNP1-3CD) FMDV O vaccine in mice and guinea pigs could induce significant cell mediated and humoral immune response. Also, immunized mice and guinea pigs were protected against the challenge virus. (C) 2009 Published by Elsevier B.V.
