We created a transgenic mouse on the FVB background in which the transgene is comprised of a strong constitutive promoter (CAG) driving expression of a dual reporter gene (luciferase and GFP). We called the original FVB mouse L2G85.
The transgenic biotracker mouse lines carry two or more broadly used reporters, and thus serve as sources for both labeled cells and tissues for transplantation and adoptive transfer experiments.
