Provided are an anti-TNFα/anti IL-17A natural antibody structure-like heterodimer form of a bispecific antibody and a preparation method therefor, wherein the antibody can bind two target molecules simultaneously, and can be used for treating complex diseases.

Anti-TNFα/anti IL-17A natural antibody structure-like heterodimer form of bispecific antibody and preparation method therefor

An anti-PD-1/anti-VEGF natural antibody structure-like heterodimeric form bispecific antibody and preparation thereof. Provided are a highly stable, heterodimeric form anti-PD-1/anti-VEGF bispecific antibody having natural IgG characteristics and free of mismatched heavy and light chains and preparation method for the antibody. The bispecific antibody is capable of simultaneously binding with two target molecules and provides improved efficacy in treating a complicated disease.

Anti-PD-1/anti-VEGF natural antibody structure like heterodimeric form bispecific antibody and preparation thereof

Provided are an anti-PD-1/anti-HER2 natural antibody structural heterodimeric bispecific antibody and a method of preparing the same. More particularly, provided are a highly stable heterodimeric anti-PD-1/anti-HER2 bispecific antibody having natural IgG characteristics without mismatch between a heavy chain and a light chain, and a method of preparing the same. The bispecific antibody may bind to two target molecules simultaneously and has excellent effects in treatment of a complex disease.

Anti-PD-1/anti-HER2 natural antibody structural heterodimeric bispecific antibody and method of preparing same

Provided are an anti-PD-L1/anti-CD47 bispecific antibody that has natural IgG characteristics and is in a highly stable heterodimer form without the heavy chain and light chain being mismatched, and a preparation method therefor. Either the first Fc chain or second Fc chain of the bispecific antibody comprises amino acid substitutions at positions 366 and 399, and the other comprises amino acid substitutions at positions 351, 407 and 409.

Anti-PD-L1/anti-CD47 bispecific antibody

Provided are an anti-PD-L1/anti-PD-1 natural antibody structure-like heterodimeric bispecific antibody and a preparation thereof. In particular, provided are a highly stable heterodimeric anti-PD-L1/anti-PD-1 bispecific antibody with characteristics of a natural IgG and without mismatches heavy chain-light chain, and a preparation thereof. The bispecific antibody can bind to both target molecules and is more effective in treating a complex disease.

Anti-PD-L1/anti-PD-1 natural antibody structure-like heterodimeric bispecific antibody and preparation thereof

The present invention provides a method for production of stable and highly specific heterodimeric immunoglobulin constructs, e.g., bispecific antibodies, retaining desirable properties of native IgG and lacking undesirable heavy chain-light chain mispairing, that can simultaneously bind two target molecules and are more potent in the treatment of complex diseases.

Heterodimeric immunoglobulin constructs and preparation methods thereof

Provided are an anti-PD-1/anti-HER2 natural antibody structural heterodimeric bispecific antibody and a method of preparing the same. Specifically, provided are a highly stable anti-PD-1/anti-HER2 heterodimeric bispecific antibody having characteristics of a natural IgG and having no mismatched heavy chain and light chain, and a method of preparing the same. The bispecific antibody may bind to both of two kinds of target molecules, and thus may be more effective in treating complex diseases.

Anti-PD-1/anti-HER2 natural antibody structural heterodimeric bispecific antibody and method of preparing the same

An antibody specifically binding to PD-1 and a functional fragment thereof. The antibody or functional fragment thereof includes a PD-1 chimeric antibody and a functional fragment thereof, and a PD-1 humanized antibody and a functional fragment thereof.

Antibody specifically binding to PD-1 and functional fragment thereof

An antibody specifically binding to IL-17A or a functional fragment thereof. The antibody or functional fragment thereof includes an IL-17A chimeric antibody and a functional fragment thereof, and an IL-17A humanized antibody and a functional fragment thereof.
