摘要: 在二次细胞融合中,经2~4次克隆后已建成28株抗恶性疟原虫(FCC-1/HN)的杂交瘤。其中针对裂殖子和成熟裂殖体抗原的McAb有9株,仅对裂殖体特异的有4株,对裂殖体和滋养体期原虫产生荧光反应的有15株。 应用间接荧光抗体技术,检查这28株McAb对7种不同疟原虫的交叉反应。结果,仅有93D4和94B5属株特异性McAb,其余各株均对恶性疟原虫(安徽株)有明显荧光反应。有5株McAb(92A3,94A2,94A6,94B3和96B5)对间日疟原虫也有交叉,而96B5株还对诺氏疟原虫和含蟹猴疟原虫产生交叉反应。

Abstract: Twenty-eight hybridoma cell lines secreting monoclonal antibodies (McAbs) against erythrocytic stage of P. falciparum were established by fusion of SP2/0 mice myeloma cells with spleen cells of BALB/c mice immunized with FCC-1/HN isolate of P. falciparum. Among these McAbs, 4 directed against schizonts only, 9 against merozoites and segments, 15 against late trophozoites and schizontes. By IFAT, 2 McAbs, 93D4 and 94B5, reacted only with homologous parasite, indicating that they might be strain-specific; while the other 26 McAbs reacted with both Hainan and Anhui isolates of P. jalciparum. Five McAbs (92A3, 94A2, 94A6, 94B3 and 96B5) cross-reacted with P. vivax. In addition, 96B5 was also cross-reactive with P. knowlesi and P. cynomolgi.
