| Research Abstract |
The DNA/polycation complexes were prepared by reaction between salmon tests DNA and polycations (Chitosan, poly-L-arginine, poly-L-histidine, poly-L-lysine, and protamine) in order to investigated the potential of the complexes for injectable scaffolds. DNA/chitosan and DNA/protamine complexes were mobile paste. These complexes including carbonate apatite were also mobile paste, and created new bone in vivo test. It is expected that DNA/chitosan and DNA/protamine complexes will be useful as biomaterials for injectable scaffolds.
