Nanobody targeting influenza a virus nucleoprotein and application thereof, and nucleic acid encoding nanobody

Abstract

Disclosed are a nanobody targeting influenza A virus nucleoprotein and an application thereof, and a nucleic acid encoding the nanobody. The present disclosure obtains one nanobody targeting influenza A virus nucleoprotein through construction of a nanobody phage library and phage screening technology. The nanobody targeting influenza A virus nucleoprotein is a VHH antibody fragment having an amino acid sequence shown in SEQ ID NO:1-SEQ ID NO:2. The nanobody in the present disclosure can specifically bind to influenza A virus nucleoprotein, and can be applied to the detection and analysis of influenza A virus, and has broad application prospects in the fields of early warning of the epidemic or outbreak of influenza A virus, as well as the detection of influenza A virus in the environment or human body.

Dependencies are inferred from the claim text.
