LOCUS       sequence-76270-e        7071 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  An AAV packaging vector that expresses channel rhodopsin 2 (H134R) 
            (fused to EYFP) under the EF1a promoter, which can be deactivated 
            (deleted) by recombination between the flanking loxP sites..
