GFP gene eukaryotic express plasmids were transfected into ES cells. The cells were observed under the inverted fluorescent microscope. The clones which expressed the powerful green fluorescence were chosen to be named ES-GFP cells and cultured continuously. The examination of ES cell totipotent including Alkine phosphatase staining, embryonic body formation in vitro and teratomas formation in nude mice was implemented.
