摘要: A non-immunized human single chain variable fragment (scFv) library containing 2.5 x 10(7) individual clones was constructed from antibody variable region genes of 200 non-immunized donors. ScFv gene repertories were generated by randomly combining rearranged variable regions of heavy chain (VH) and natural occurring light chain (VL) using overlapping extension PCR (OE-PCR). Five recombinant protein antigens from different species were successfully used to select specific binders. Phage ELISA showed that the recombinant phage particle could specifically bind to non-structural protein 1 of Avian influenza virus. This method can therefore efficiently generate a phage antibody library.
