Abstract

To prepare monoclonal antibody (mAb) against prM epitope. The gene encoding prM was isolated using RT-PCR from brain of JEV infected mouse and cloned into prokaryotic expression vector pET-32a. Recombinant plasmid was transformed into E.coli BL21/DE3/LysS, then the transformed cells were expressed with the induction of IPTG. The expression and purification of the prM protein was analyzed by SDS-PAGE. The BALB/c mice were immunized with purified prM protein. Hybridoma cell lines secreting monoclonal antibodies against prM were established after cell fusion of mouse splenic cell and P3-X63-Ag8.653 cells. The specificity of mAb was identified by ELISA, Western Blot and Immunohistochemistry assay. mAb against prM epitope of JEV was prepared successfully. The obtained prM specific mAb was valuable for the prevention and dignosis of Japanese encephalitis.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
