Figure 6From: Production and purification of immunologically active core protein p24 from HIV-1 fused to ricin toxin B subunit in E. coliLevels of IgG antibodies anti-p24 after intraperitoneal immunization. BALB/c mice were immunized at the days indicated by arrows, with 15 μg of p24 (filled squares) or 30 μg of RTB/p24 in the presence (filled triangles) or absence (open triangles) of CFA/IFA. As negative control mice were inoculated with PBS (filled rhombus). Serum samples were diluted at 1/200, and levels of IgG anti-p24 antibodies were determined by ELISA. All sera samples were tested in triplicate and standard deviations are included.Back to article page
