Expression levels of ID1-ID2a producing S2 monoclonal cell lines.

<p>Bars indicate the yield of protein in the culture supernatant of stable transfected S2 clones. The values were determined by testing titrations of culture supernatant compared to a standard protein solution in sandwich ELISA using one monoclonal ID1-ID2a specific antibody to capture and another monoclonal ID2-ID2a specific antibody as a the target of a tertiary layer of horse radish peroxidase conjugated antibodies.</p

Comparison of the induction of binding inhibitory antibodies against antigens expressed in High-Five or S2 cells.

<p>Bars indicate the mean binding inhibition of 3D7 (A) or FCR3 (B) <i>Plasmodium falciparum</i> infected erythrocytes (IE). The values are the percentages of released IEs in wells with test serum compared to wells with control serum from non-immunized animals. Serum was used in a one to ten dilution. Error bars indicate the coefficients of variation of the mean of triplicate measurements (100*(SD/(mean of control binding)).</p
