title: Monoclonal antibodies to the influenza A virus nucleoprotein affecting RNA transcription.
abstract: Monoclonal antibodies were used to map the antigenic domains of the A/WSN/33 (HoN1) influenza virus nucleoprotein. Three nonoverlapping antigenic regions of the nucleoprotein were identified by using competitive-binding enzyme-linked immunosorbent assays. Monoclonal antibodies to two nucleoprotein domains inhibited in vitro transcription of viral RNA, suggesting that these specific regions of the nucleoprotein are topographically or functionally involved in RNA transcription.
