rAAVs exhibit differences in GFP production in MPS IIIB brain as indicated by resulting GFP intensity. Mid-sagittal sections of 3-month-old MPS IIIB animals were used to quantitate intensity of AAV-based GFP production. GFP intensities in the cortex, hippocampus, thalamus and cerebellum of each animal were summed. Data were analyzed by one-way ANOVA. **P<0.01, $P<0.0001. Data represented as mean±s.e.m., N=3/serotype.
