Figure 3.
Zebrafish embryos were microinjected with circular type plasmid pCMV-pax6in-eGFP and linearized plasmid which had the insertion fragment removed from between the CMV promoter and the eGFP reporter gene. A: Zebrafish embryos microinjected with circular type plasmid pCMV-pax6in-eGFP (no fluorescence was observed). B: Zebrafish embryos microinjected with linearized plasmid which had the insertion fragment removed from between the CMV promoter and the eGFP reporter gene in the pCMV-pax6in-eGFP plasmid. Re-expression of eGFP was observed as the embryo emitted fluorescence.
