Figure 4From: Analysis of IgG with specificity for variant surface antigens expressed by placental Plasmodium falciparum isolatesComparison of antibody levels in surface recognition and CSA biding. CSA adhesion activities (â– ) and the corresponding anti-VSA levels (â–¡) measured as mean fluorescent intensities of plasma obtained from primiparous women presented with infected placentas are shown. High CSA binding also stands for low anti-CSA adhesion activity. Plasma samples from a semi-immune nulligravid woman and a male served as controls.Back to article page
