ABSTRACT
Objective To construct human phage antibody library against hepatoma carcinoma.Methods Peripheral blood mononuclear cells(PBMCs) of patients with liver cancer were sensitized in vitro and transformed by Epstein-Barr virus(EBV).The genes of light chain and Fd of antibodies were amplified by RT-PCR.Fab genes were cloned into vector pComb3 and transformed into E.coli XLI-Blue by electroporation to construct the Fab-displaying phage antibody library.Results ELISA detection showed that 4 liver cancer patients' B cells transformed by EBV could produce specific antibodies to hepatoma carcinoma cell.Totally 13 types of light chain genes and 28 types of Fd genes were obtained by RT-PCR.The capacity of the primary phage library was 1.7?107pfu/mL.The percentage of recombinant clones was about 100%.Conclusion A human phage antibody library has been constructed successfully by means of EBV transformation technique.
