ABSTRACT
Objective:To clone human anti-ricin antibodies from large phage antibody library.Methods:Panning for a large phage library against ricin toxin was conducted to select specific antibodies against ricin. The binding activities and specificities were tested by ELISA method. Soluble ScFvs were prepared through infecting E coli. HB2151 with the selected phage antibodies and induction with IPTG. Results:Forty positive clones were obtained after 5 rounds of panning, and 12 clones had specific binding ability to ricin toxin. DNA fingerprinting showed 7 different band patterns indicating 7 different positive clones. DNA sequencing showed that variable regions of these ScFvs belonged to different subgroups.Conclusion:Human anti-ricin antibodies were successfully obtained from large phage antibody library.
