A plasmid construct with the green fluorescence protein (GFP) gene driven by the medakafish beta-actin gene promoter was successfully introduced into eggs, and the expression of GFP was observed in 20% of the primary transfectant (chimera) fish. In addition, germ line transmission of GFP was observed in 13% of the GFP-positive primary transfectant fish. The new application described here should enable us to investigate gene expression using the fish model on a routine basis without high technical sophistication.}, pages = {285--293}, title = {Introduction of a foreign gene into medakafish using the particle gun method}, volume = {287}, year = {2000} }
