Research Abstract

We have generated mortalin specific antibodies that showed cell-internalizing features. These antibodies were validated as nano-carriers. Antibodies were conjugated with quantum dots, FITC and expression plasmids that were delivered to cancer cells successfully. Cancer cells were labeled with various kinds of quantum dots to generate multicolor cells for long term imaging. We have demonstrated that (1) the antibody can be used for optic tagging of cells with quantum dots, (2) the optically tagged cells can be used for long term imaging of cells and (3) the tagged cells undergo normal differentiation in vitro and in vivo.
