β-Galactosidase activity and vector genome copy number in the livers and spleens of mice 48 hours following injection of various doses of HDΔ28E4LacZ into mice pretreated 30 minutes prior with either saline or VIP (10 nmol/mouse) by intraperitoneal injection. Means ± SD shown (n ≥ 5). Background β-galactosidase activity (no vector control) was 12.5 ± 2.5 U/g protein for the liver and 9.3 ± 0.5 U/g protein for the spleen. Vector genome was undetectable in no vector control animals. VIP, vasoactive intestinal peptide; vp, vector particles.
