A panel of 15 recombinant single chain antibodies (scFv) specific to grapevine virus B (GVB) were recovered from a human combinatorial scFv antibody library using the phage display technique against purified virus particles. Two selected scFv-encoding genes were expressed in recombinant Escherichia coli cells as dimeric antibodies. Successful detection of GVB in tissues of herbaceous hosts and grapevine was obtained in a direct binding assay using dimeric scFvs. This reagent was also shown to substitute efficiently for a GVB polyclonal serum in standard DAS-ELISA test used routinely for diagnosis.
