Canine parvovirus nanobody CPV-VHH-E3 and application thereof

Abstract

Provided are a canine parvovirus (CPV) nanobody CPV-VHH-E3 and application thereof, belonging to the technical field of immunology. The nanobody CPV-VHH-E3 includes heavy chain variable region with amino acid sequence as shown in SEQ ID NO: 1, and a nucleotide sequence of a gene encoding the nanobody CPV-VHH-E3 is shown in SEQ ID NO: 2. The present application constructs a nanobody immune library for CPV by phage-display technology, and obtains specific anti-CPV nanobody CPV-VHH-E3 by screening, which is verified to specifically bind CPV through experiments, and is applicable to develop a nanobody preparation for clinical diagnosis and treatment of CPV, providing a certain theoretical support for the application of nanobodies in the field of veterinary biological products.
