Abstract：Using a Dual-View wavelength splitter, double-stained African green monkey kidney COS-7 cells, transfected with pEGFP-Myosin 15a and costained with Rhodamine-filopodia were observed based on an ICCD(intensified charge couple device) fluorescence micro-imaging systems. Total internal reflection fluorescence microscopy was used to observe the overexpression of Myosin 15a to the tips of the elongation filopodia. An approach to collecting fluorescence in two channels and avoiding spectra crosstalk was employed to observe Myosin 15a and filopodia distribution in African green monkey kidney COS-7 cells. High sensitivity TIRF technology and two channels imaging method provided a wide application in bio-medical studies.
