Kinetics of antigen-specific serum IgG production following immunization with water-in-oil emulsion-based (a) or cationic-liposome-based (b) adjuvant formulations. Animals were immunized at weeks 0 and 4. At week 14, the group immunized with BCG was boosted with an immunization of antigen formulated in ISA70. Points represent the mean (±standard error) Rv3019c-specific serum IgG levels, as measured by optical density at 450 nm (OD 450nm).
