ABSTRACT
AIM:
To Screen and identify human single-chain variable fragment (ScFv) specific to hepatitis B virus core protein and determine its gene sequence.METHODS:
The recombinant phages were panned by HBcAg coated in a 96-pore plate and 48 clones were identified specific to HBc after three rounds of panning. The specificity of ScFv from the positive clone was determined by ELISA. Then, the soluble ScFv was expressed in E.coli. HB2151 and secreted in the supernatant. Subsequently, SDS-PAGE and dot blot were performed to identify the ScFv in the supernatant and cell lysate. The gene of ScFv specific to hepatitis B virus core protein was sequenced.RESULTS:
The ScFv screened from phage antibodies has a specific combination character with hepatitis B virus core antigen. Soluble ScFv was confirmed to express in E.coli. HB2151 and secrete in the supernatant. The sequence of ScFv gene conformed to that of heavy chain and kappa chain of human immunoglubulin.CONCLUSION:
Human ScFv specific to hepatitis B virus core protein has been identified by means of the phage display technology, and its gene sequence has been determined.
