Abstract

Novel influenza A virus (H10N8) infected human with fatality in China during 2013-2014. It is important to detect such nonprevalent subtype influenza A virus in clinic and regular surveillance in the early stage for effective control and prevention from the potential pandemic. Unavailability of convenient rapid diagnosis for this subtype virus in resources-limited setting is an obstacle for timely recognizing human case. In the present study, a panel of mouse H10 specific monoclonal antibodies (mAbs) was generated, two of which were used to develop a sandwich enzyme-linked immunosorbent assay (ELISA) for detecting the hemagglutinin of avian influenza A (H10N8) virus. ELISA results showed high sensitivity with the lowest detection limit of 0.5HAU/50 μL for live virus, which laid a foundation for clinic use as a promising diagnostic methodology.

Keywords: H10 subtype; hemagglutinin; monoclonal antibody; sandwich ELISA.
