  • Recombinant antibodies against infectious bursal disease virus (ibdv)
    Patent number: 7449556
    Abstract: The purpose of this project was to isolate recombinant antibodies for diagnosis of very virulent infectious bursal disease virus (vvIBDV) in fixed tissues. Phage-displayed recombinant antibodies, comprised of the single chain variable fragment (scFv), were investigated. A previously made recombinant antibody library generated against vvIBDV was selected and screened for recombinant antibodies that reacted against vvIBDV in ELISA. A new library was constructed fom chickens immunized with fixed vvIBDV and also screened for recombinant antibodies against vvIBDV. Also, a previously identified recombinant antibody, known to react well with vvIBDV, was used to replace either the Vh or VI gene with corresponding fragments from a new library. The Vh and VI antibody genes were initially amplified effectively by PCR. No new recombinant antibody clones were isolated from the libraries generated against vvIBDV.
