Fig 10. Serum OVA-specific IgG titers.
IgG was measured after IN immunization with 20% NE with 20 μg of OVA or OVA alone. Immunizations were performed at 0 and 4 weeks (after the 4 week serum collection). (A) CPC/Tween80 1:6, (B) DODAC/Tween80 1:6, (C) DODAC/Tween80 1:1, (D) CPC/P188 1:6, (E) DODAC/P188 1:6, (F) DODAC/P188 6:1, (G) CTAC/P188 1:6, (H) DODAC/P407 1:1, (I) CAB/Tween80 1:6, (J) OVA alone. Geometric means are indicated±95% Cl. (K) Endtiter geometric means plotted ±95% Cl.
