The present invention relates to a novel antibody library and an antibody-screening method using same. Having a human sequence-derived specific VH or VL scaffold, the antibody library according to the present invention exhibits high thermodynamic stability and enjoys the advantages of allowing high soluble expression as well as reversible folding. In addition, the antibody according to the present invention includes a variety of rationally controlled CDRs so as to exhibit high specificity and high affinity to all antigens and thus can be advantageously used for selecting an adequate candidate antibody against a target antigen.

Antibody library and antibody screening method using same

The present invention relates to an antibody specifically bound to mesothelin (MSLN), a nucleic acid encoding the antibody, a vector and a host cell including the nucleic acid, a method for producing the antibody, and a pharmaceutical composition for treating cancer or tumor including the antibody as an active ingredient. The antibody specifically bound to the mesothelin according to the present invention has high affinity and specificity to an antigen, such that it is possible to develop an antibody effectively usable for treatment or diagnosis of cancer or tumor diseases.

Anti-mesothelin antibody and composition comprising the same

The present invention relates to an antibody specifically binding to glypican 3 (GPC3), a nucleic acid encoding the antibody, a vector and a host cell containing the nucleic acid, a method of preparing the antibody, and a pharmaceutical composition for treating cancer or tumor, containing the antibody as an active ingredient. The antibody specifically binding to glypican 3 according to the present invention may be effectively used to treat cancer or tumor, particularly, hepatocellular carcinoma due to high affinity and specificity to glypican 3.

Anti-glypican 3 antibody and pharmaceutical composition containing the same

The present invention relates to an antibody that binds specifically to a tissue factor pathway inhibitor (TFPI), a nucleic acid encoding the antibody, a vector comprising the nucleic acid, a host cell transformed with the vector, a method for producing the antibody, and a pharmaceutical composition for treating hemophilia, which comprises the antibody as an active ingredient. The antibody of the present invention, which binds specifically to TFPI, can activate the extrinsic pathway of blood coagulation by inhibiting TFPI. Thus, the antibody of the present invention can be effectively used for the treatment of antibody-induced hemophilia patients and for the prevention of blood coagulation disease in hemophilia-A or hemophilia-B patients.

Antibody binding to TFPI and composition comprising the same

There are provided a method named Tat-associated protein engineering (TAPE), of screening a target protein having higher solubility and excellent thermostability, in particular, an immunoglobulin variable domain (VH or VL) derived from human germ cells, by preparing a gene construct where the target protein and an antibiotic-resistant protein are linked to a Tat signal sequence, and then expressing this within, and human or engineered VH and VL domain antibodies and human or engineered VH and VL domain antibody scaffolds having solubility and excellent thermostability, which are screened by the TAPE method. There are also provided a library including random CDR sequences in the human or engineered VH or VL domain antibody scaffold screened by the TAPE method, and a preparing method thereof. There are also provided a VH or VL domain antibody having binding ability to the target protein screened by using the library, and a pharmaceutical composition including the domain antibody.
