Abstract

There is a growing demand for the development of new bio-analytical technique that is capable of monitoring neuronal differentiation non-invasively, in real-time and without any fluorescent or radioactive probes. To fulfill these promises, efficient and easy protocols to monitor neuronal differentiation have to be developed. In this study, we demonstrated a rapid and label-free detection method to monitor neuronal differentiation by high-resolution 2Dsurface plasmon resonance sensing technology with a CCD camera to analyzing refractive index change of PC12 cells. We have successfully monitored the intracellular translocation of PKC in PC12 cells by 2D-SPR and found that the cells treated with differentiation factor, nerve growth factor (NGF) showed a remarkable enhancement of SPR response to muscarine and carbacol stimulation. Our results suggested that 2D-SPR imager might be applicable to monitor neuronal differentiation and to study the expression state of the specific receptors in living state.
