Experiment Testing virus region 8 (VR8) mutant cross-species compatible Adeno Associated Viruses (ccAAVs) in mice. Experiment Condition AAV9 GFP Assay Description: Native fluorescence was quantified using Image J. For each animal, 6 images were taken from 2 sections and used to calculate corrected total cell fluorescence using the formula: Integrated Density – (Area of selected image X Mean fluorescence of background readings).
