  • Publication number: 20190389973
    Abstract: The present disclosure relates to a novel multi-specific binding protein, specifically, a novel multi-specific binding protein prepared by supplementing drawbacks of various conventionally disclosed multi-specific binding proteins, for example, a bispecific binding protein, more specifically, a novel multi-specific binding protein including a polypeptide, wherein heavy chain CH1 domain and CL domain of a antibody constant region are not included but a heavy chain variable region and/or a light chain variable region are consecutively linked in the polypeptide.

  • Patent number: 10087248
    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.

  • Publication number: 20140072558
    Abstract: The present invention relates to an activin receptor type II B (ACVR2B) inhibitor which comprises the delta-like 1 homolog (DLK1) extracellular water-soluble domain. More specifically, the present invention relates to an extracellular soluble domain of DLK1; fragments of the extracellular soluble domain of DLK1; mutants of the extracellular soluble domain of DLK1; a composition for suppressing ligand linkage with the ACVR2B receptor, which includes a fragment of the mutants as an active ingredient; and a pharmaceutical composition for prevention and treatment of diseases which comprises the same. The composition of the present invention competitively binds to the ACVR2B receptor and inhibits the binding of an ACVR2B ligand to the ACVR2B receptor, which inhibits protein signalling associated with such ligands, and will be useful for prevention and treatment of diseases associated therewith.
