چکیده انگلیسی
To construct phage antibody library for VP3 protein of duck hepatitis virus type 1(DHAV-1) and pan the specific single-chain variable fragment antibody (scFv), total RNA was extracted from the protein VP3- immunized mice spleen., vp3 gene encoding VP3 protein was amplified from the genome of DHAV-1 by RT-PCR method for the following recombinant pET-VP3 construction, immunogenic VP3 expression and purification, and combined with SOE-PCR method to complete the assembly of scFv. The scFv gene was cloned into pCANTAB5E vector for phage antibody library construction. Finally, the library for anti-VP3 scFv was screened by four rounds of adsorption-elution-enrichment with the purified VP3 protein. The characters of binding ability, specificity and neutralization of soluble antibodies expressed were evaluated by ELISA. The results showed 7 VP3-specific scFvs have been screened and identified with high both sensitivity and specificity for binding DHAV-1. To our knowledge, this is the first report for VP3-specific scFv of DHAV-1 and potentially promising application used in prevention and treatment of duck viral hepatitis.
