pAAV-EF1a-double floxed-EYFP-WPRE-HGH pA (Addgene plasmid 20296) was made into AAV serotype 5 at >1010 GC/ml by Salk Institute Viral Vector Core using standard protocols (referred to as AAV DIO-eYFP). Girk2a-EYFP and Snx27b-ires-GFP were sub-cloned into this vector in at Nhe1 and Asc1 sites and also generated into AAV serotype 5 virus (referred to as AAV DIO Girk2a-eYFP and AAV DIO Snx27b-ires-GFP).
