Research Abstract

A new probe which detectable for fluorescence, chemiluminescence and magnetic resonance (MR) imaging was constructed and evaluated in this study. The fusion of a fluorescent protein to a chemiluminescent protein and ferritin as iron indicator has enabled to pursue the transplanted cells at in vivo. Since the novel probe which possess three kinds of function have worked well, we are preparing the new publication of the novel in vivoimaging method using Venus of fluorescent protein as expression marker, luciferase as live cell marker and ferritin protein as MRI marker.
