Figure 2From: Improved long-term expression from helper virus-free HSV-1 vectors packaged using combinations of mutated HSV-1 proteins that include the UL13 protein kinase and specific components of the VP16 transcriptional complexThe stabilities of expression in the striatum supported by pNFHlac packaged using specific combinations of mutated HSV-1 proteins. For each time point and packaging condition, the graph shows the % of X-gal positive cells at 4 days (mean number of X-gal positive cells at 2 weeks, or 1, 2, or 3 months after gene transfer divided by the mean number of positive cells at 4 days (× 100); calculated using the data in Table 1).Back to article page
