hM3-mCherry is expressed eutopically in vGluT2-Cre, ChAT-Cre, and vGAT-Cre mice. In vGluT2-cre mice, FISH for vGluT2 mRNA colocalizes with mCherry immunostaining. In ChAT-Cre mice, immunostaining for ChAT colocalizes with mCherry. In vGAT-Cre mice, FISH for vGAT mRNA colocalizes with mCherry. Scale bar, 100 μm.
