Production and characterization of anti-dengue capsid antibodies suggesting the N terminus region covering the first 20 amino acids of dengue virus capsid protein is predominantly immunogenic in mice
We produced monoclonal and polyclonal antibodies to the capsid (C) protein of dengue serotype 2 virus (DV2 C). First, a maltose-binding protein fused to DV2 C protein (MBP-C) was overproduced in E. coli. The affinity-purified MBP-C protein was cleaved by factor Xa protease to obtain a recombinant DV...

| Summary: | We produced monoclonal and polyclonal antibodies to the capsid (C) protein of dengue serotype 2 virus (DV2 C). First, a maltose-binding protein fused to DV2 C protein (MBP-C) was overproduced in E. coli. The affinity-purified MBP-C protein was cleaved by factor Xa protease to obtain a recombinant DV2 C protein, which was then used for mouse immunizations. Two hybridoma cell lines producing anti-C Mabs as well as anti-C polyclonal antibody were successfully generated and characterized. Interestingly, all of the generated antibodies specifically recognized the first 20 amino acids of the DV2 C protein, as determined by peptide epitope mapping and via a recombinant DV2 C protein in which this region was deleted. The results suggested that this region is predominantly immunogenic in mice. © Springer-Verlag 2009. |
