Fig. 4.

IgG2a antibody response and amino acid homology to recombinant MSP-1₁₉ antigen from clone AS. Antibody titre shown as black bars and left y-axis was calculated as the reciprocal of the greatest dilution at which O.D was greater than the mean plus 2 standard deviations of the O.D for control mouse sera at 1/100 dilution. Figure shows mean and standard error of n = 5–6 infected mice per clone. Groups not connected by the same letter denote pairs that are significantly different (P < 0.05) according to Tukey’s Pairwise analysis. The black line and right y-axis show the proportion of amino acid sequence homology to the MSP-1₁₉ recombinant antigen from clone AS.
