Liver apob mrna levels were quantified relative to GAPDH mrna three days after i.v. administration of sirna. Data are mean values relative to the saline treatment group ± s.d. Chol-siApoB- 1 was administered at doses of, 5, 25, or 12.5 mg/kg (n = 6 per group) (a) and SNALP siapob-1 was administered at sirna doses of 1,.5,.25 and.1 mg/kg (n = 4 per group) (b). 12 %Injected Dose 8 6 4 Sense Antisense 2.25.5 1 2 4 6 8 12 Time (h) Supplementary Figure 2.

Plasma clearance over a 24 h period of the sense and antisense strands of siapob-2 in animals treated with 2.5 mg/kg SNALP siapob-2 (n = 2). The time course is shown extending to 12 h as no sirna was detected at 24 h. Each data point represents the group mean ± s.d. of the percent injected dose.

Uniform biodistribution and silencing activity of SNALPsiApoB-2 in liver. ApoB mrna and siapob-2 accumulation were quantitated in 12 separate liver biopsy samples collected from the left lateral lobe (LL), median lobe (M), right lateral lobe (RL) and caudate lobe (C) 24 h after animals were treated with either saline or 2.5 mg/kg SNALP siapob-2. ApoB mrna was quantified relative to GAPDH mrna. Data are mean values for three measurements per liver biopsy ± s.d.
