    Abstract: The present invention relates to a TNF-? (tumor necrosis factor-alpha)/CXCL-10 (C-X-C motif chemokine 10) double targeting antibody based on the IgG format. Specifically, it was verified that an antibody, in which scFv having a heavy chain variable domain and a light chain variable domain of the CXCL10 specific antibody links to the C-terminus of the heavy chain constant domain of the TNF-? specific antibody, is a bispecific antibody that effectively binds to both TNF-? and CXCL10, and thus the antibody can be useful as a double targeting antibody capable of identifying TNF-?/CXCL10. A composition of the present invention comprises a TNF-?/CXCL-10 double targeting antibody which effectively binds to both TNF-? and CXCL10. The double targeting antibody of the present invention has excellent TNF-? inhibitory activity and osteoclast differentiation inhibitory activity compared with the TNF-? or CXCL10 single targeting antibody.
