egIs1 [dat-1p::GFP]; reportedly maps to LG IV. Bright GFP observable in dopamine neuronal soma and processes. For some reason this strain is resistant to neurotoxic effects of 6-OHDA compared to an independent strain BY200 (Nass et al., 2002). Or maybe BY200 is more sensitive to 6-OHDA due to its co-injection marker gene rol-6?
