猪流行性腹泻病毒S蛋白单克隆抗体的制备和鉴定
Preparation and characterization of a monoclonal antibody strain against the S protein of porcine epidemic diarrhea virus
摘要
Abstract
To further investigate the mechanisms of porcine epidemic diarrhea virus(PEDV)infec-tion,PEDV S1 protein was expressed by a CHO eukaryotic expression system.Then the purified recombinant protein was used to immunize BALB/c mice.Following cell fusion,a monoclonal antibody specific to the PEDV S1 protein was screened.Indirect immunofluorescence and Western-blot analysis further confirmed that the monoclonal antibody could specifically recognize the PEDV S protein.In conclusion,a mono-clonal antibody against PEDV S1 protein were successfully prepared,which laid a foundation for the de-tection and further research of PEDV.关键词
