Antigen capture enzyme-linked immunosorbent assay (ELISA) is one of the most useful methods to detect Ebola virus rapidly. We previously developed an antigen capture ELISA using a monoclonal antibody (MAb), 3-3D, which reacted not only to the nucleoprotein (NP) of Zaire Ebola virus (EBO-Z) but also to the NPs of Sudan (EBO-S) and Reston Ebola (EBO-R) viruses. In this study, we developed antigen capture ELISAs using two novel MAbs, Res2-6C8 and Res2-1D8, specific to the NP of EBO-R. Res2-6C8 and Res2-1D8 recognized epitopes consisting of 4 and 8 amino acid residues, respectively, near the C-terminal region of the EBO-R NP. The antigen capture ELISAs using these two MAbs detected the EBO-R NP in the tissues from EBO-R-infected cynomolgus macaques. The antigen capture ELISAs using Res2-6C8 and Res2-1D8 are useful for the rapid detection of the NP in EBO-R-infected cynomolgus macaques.
抗原捕获酶联免疫吸附测定(ELISA)是快速检测埃博拉病毒最有用的方法之一。我们之前利用单克隆抗体(MAb)3-3D开发了一种抗原捕获ELISA,该抗体不仅能与扎伊尔埃博拉病毒(EBO-Z)的核蛋白(NP)发生反应,还能与苏丹埃博拉病毒(EBO-S)和雷斯顿埃博拉病毒(EBO-R)的NP发生反应。在本研究中,我们利用两种针对EBO-R NP的新型MAb,即Res2-6C8和Res2-1D8,开发了抗原捕获ELISA。Res2-6C8和Res2-1D8分别识别EBO-R NP C端区域附近由4个和8个氨基酸残基组成的表位。使用这两种MAb的抗原捕获ELISA检测了EBO-R感染食蟹猴组织中的EBO-R NP。使用Res2-6C8和Res2-1D8的抗原捕获ELISA可用于快速检测EBO-R感染食蟹猴中的NP。
