LOCUS       sequence-399618-        6840 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  An adeno-associated viral vector expressing Cre-dependent 
            channelrhodopsin-2 fused to a V5 epitope and the ligand-binding 
            domain of estrogen receptor (ChRERa) from a synapsin promoter, for 
            use in PET.
