Figure 4. Az and known adjuvants increase antigen-specific antibody production.
C57BL/6 mice were i.p. injected with KLH (100 μg/mouse) or OVA (100 μg/mouse). The immunized mice were i.p. injected once with Alum (33.0 mg/kg mouse), Az (2.25 mg/kg mouse) or PolyI:C (6.65 mg/kg mouse). Boost immunization was performed by using the same protocol as prime immunization at 3 weeks after prime immunization. Sera were collected at the indicated times. Production of total IgG, IgG1 and IgG2c antibodies specific to (a) KLH or (b) OVA was determined by using an ELISA (●; No adjuvant,
; Alum,
; Az,
; PolyI:C). Graphs show mean ± s.e.m. Data shown in (a,b) are representative of three independent experiments (n = 3–5 mice per group in each experiment). *p < 0.05; **p < 0.01; ***p < 0.001.
