This double transgenic strain was established by co-injection of CAG-EGFP and mouse Acr-EGFP into F344/NSlc at Osaka University (over 5 generations, Dec 2016). There are two lines; GBGS(green body, green sperm)#2 and GBGS #6, but copy numbers and insertion site are not identified. Both lines show enough intensity of GFP fluorescence (no quantitative data).
