Absorption experiments with washed membranes derived from erythrocytes infected with schizonts of Plasmodium knowlesi (PE) showed that the antigen responsible for agglutination of PE in SICA tests is firmly bound to membranes. Further experiments demonstrated that the number of antibody binding sites at the surface of parasitized erythrocytes can be measured using iodinated globulins. The conditions under which this could be achieved have been defined and a preliminary estimate of the number of high affinity surface antigen sites (greater than or equal to 10(4) per cell) has been made. Suggestions are given for further work to obtain a more accurate value.
用感染诺氏疟原虫裂殖体的红细胞（PE）来源的洗涤膜进行的吸收实验表明，在SICA试验中导致PE凝集的抗原与膜紧密结合。进一步的实验证明，可以使用碘化球蛋白来测量被寄生红细胞表面的抗体结合位点数量。已经确定了实现这一点的条件，并对高亲和力表面抗原位点的数量（每个细胞大于或等于10⁴）进行了初步估计。文中给出了进一步工作的建议，以获得更准确的值。
