Abstract:
Objective To provide the candidate antigens for immunological diagnosis by analyzing the expression of nu -cleoprotein ( NP) of Ebola virus. Methods BioSun software was used to predict the NP epitopes. The bridging-PCR was used to synthesize the NP gene. The pBVIL1 vector was used to clone and express the NP gene. Results The 360-739 aa of NP was confirmed to be the dominant antigen by BioSun software. The recombinant NP dominant antigen was expressed in E.coli with molecular weight of 58 ×103.The specificity of ELISA based on recombinant NP was 99.24% (130/131) in negative samples. Conclusions The dominant NP antigen can be potentially used for developing Ebola virus diagnostic reagent.
