Screening and identification of anti-HRPII single chain Fv antibodies of Plasmodium falciparum / 细胞与分子免疫学杂志

ABSTRACT

To develop simple, rapid, and efficacious diagnostic methods for malaria is one of the remaining key tasks for malaria control. Previously, we have created a phage-displayed antibody library against Plasmodium falciparum. Six clones of antibody with good reactivity to HRP-II in ELISA were isolated from the library after 3 rounds of enrichment. Soluble ScFvs were produced and the characteristics were determined. The results of Western blot showed that they could bind to HRP-II specifically and had a relative molecular mass(Mr) about 31 000. The work provided a solid fund for diagnostic kit development for malaria.
