Potential of Nanoparticles Chitosan for Delivery pcDNA3.1-tat

The development of Jembrana disease vaccine is importance to prevent the loss of Bali cattle industry in Indonesia. This study aims to prepare a Jembrana DNA vaccine. The data Tat protein sequences gained from NCBI and the consensus process has been finished by the MultAlign program, and then Cloning of the pcDNA3.1-tat has been successfully performed on E. coli DH5α and confirmed by PCR, restriction analysis and sequencing. The propagated plasmids were prepared as DNA-chitosan complex and physiochemical characterized using Particle Size Analyzer. Complex with a 1:2 (wt/wt) ratio of DNA and chitosan have a mean diameter of 268.5 nm and zeta potential +25.1 mV and the value of Cytotoxicity Assay 80-90% as compared to the untreated cells that used as negative control, so it can be concluded that nanoparticles chitosan has good potential as a carrier agent for pcDNA3.1-tat.
