The Genetic Tools Atlas (GTA) is a searchable web tool representing information and data on enhancer-adeno-associated viruses (enhancer AAVs) and mouse transgenes developed and tested at the Allen Institute for Brain Science. The GTA offers a large genetic toolkit for selective gene expression in brain cell types of interest.
