Anti-HGF/SF humanized antibody
The inventive anti-HGF/SF humanized antibody prepared by displaying on the surface of a phage an anti-HGF/SF chimeric Fab library comprising a set of human antibody light chain variable region (VL) and human antibody heavy chain variable region (VH) which are grafted with heavy chain complementary determining regions (HCDRs) of an anti-HGF/SF antibody of an animal other than human, has the equal or greater binding affinity than that of the parent anti-HGF/SF antibody, the neutralizing activity inhibiting the binding of HGF/SF to its receptor, cMET while having the reduced immunogenicity in human. Therefore, the inventive anti-HGF/SF humanized antibody can be used for preventing and treating diseases effectively, e.g., cancers, by the action of binding HGF/SF to cMET.
