ABSTRACT
Objective To screen a human single-chain variable fragments(scFv)against antiGBM antibody.Methods Using phage display technique,the phage antibody library was panned by antiglomerular basement membrane(GBM)antibody which was coated in a micro-titer plate,one clone was found to have high affinity to anti-GBM antibody.The DNA sequence of the positive clone was determined.Results Along with the increase of rounds anti-GBM antibody specific phage antibody was highly enriched and screening efficiency was increased 137 folds than the firest round.ELISA and competition inhibition assay showed that the scFv had a specific combination character with anti-GBM antibody.DNA sequencing confirmed that the whole gene of scFv was 750 bp,and in accordance with humanized single-chain variable region antibody sequence structure.Conclusion The results suggested that the scFv fragment to anti-GBM antibody could be successfully selected by recombinant phage antibody technique,which will laid an experimental foundation for further research of the therapy of Goodpasture syndrome.
