Fig. 3: EGFP DNA levels in peripheral tissues following IN and IV AAV delivery.

Copy numbers were quantified in the nasal tissue, lung, heart, liver, stomach, intestine, kidney, and spleen of Swiss (top), BALB/c (middle), and C57BL/6 J (bottom) mice. DNA levels are given as a ratio of EGFP copies to 1000 mouse beta-actin (mActb) gene copies. Data are presented as mean ± SEM (N = 5 mice per group). Nonparametric multiple t-tests were used to analyze this data, and the Mann-Whitney test was used to compare ranks between each group (*p < 0.05, **p < 0.01).
