The present invention provides multivalent and multispecific binding proteins that are capable of binding two or more antigens, or two or more epitopes. The present invention also provides methods of making and using such multivalent and multispecific binding proteins, including methods of using such binding proteins for prevention or treatment of various diseases, or for detecting specific antigens in vitro or in vivo.

Provided are compositions for increasing the half-life of a polypeptide or polypeptides in a canine and methods of their use. The compositions involve variant canine IgG Fc regions.

The present disclosure provides for antibody-oligonucleotide conjugates, methods of preparation thereof, and methods of use thereof. Also provided are related compounds, compositions and kits.

Antibody-drug conjugates, compositions thereof, and methods use. The antibody-drug conjugates include a fusion protein comprising an antibody covalently linked to an ADP-ribosyl cyclase protein via a peptide linker moiety at one or more of a C-terminus or N-terminus of a heavy or light chain of the antibody, a NAD or NMN analogue, and a payload such that the NAD or NMN analogue is conjugated to both the payload and the ADP-ribosyl cyclase protein.

The present invention provides antibodies, or antigen-binding fragment thereof, which specifically bind to tumor necrosis factor (TNF)-like ligand 1A(TL1A) The invention further provides a method of obtaining such antibodies and nucleic acids encoding the same. The invention further relates to compositions and therapeutic methods for use of these antibodies for the treatment and/or prevention of TL1A mediated diseases, disorders or conditions.

The present invention relates to an anti-MUC1 antibody binding specifically to Mucin 1 (MUC1) or an antigen-binding fragment thereof, an antibody-drug conjugate or bispecific antibody comprising the antibody, a pharmaceutical composition for prevention or treatment of cancer, comprising the same antibody, conjugate or bispecific antibody, and a nucleic acid encoding the same antibody, a vector and a host cell, both carrying the same nucleic acid, and a method for preparing an anti-MUC1 antibody or an antigen-binding fragment thereof, using the same vector and host cell. According to the present invention, the antibody shows outstanding affinity and binding force to MUC1 and the antibody-drug conjugate can bind specifically to a MUC1-expressing cell to specifically or selectively transfer the drug with efficacy. Therefore, the anti-MUC1 antibody and the antibody-drug conjugate according to the present invention can be usefully applied to the treatment of a MUC1-related disease, for example, cancer.

The present disclosure relates generally to immunoglobulin-related compositions (e.g., antibodies or antigen binding fragments thereof) that can bind to and neutralize the activity of L1-CAM protein. The antibodies of the present technology are useful in methods for detecting and treating a L1-CAM-positive cancer in a subject in need thereof.

The present disclosure is generally directed to compositions that include antibodies, e.g., monoclonal, antibodies, antibody fragments, etc., that specifically bind a TREM2 protein, e.g., a mammalian TREM2 or human TREM2, and use of such compositions in preventing, reducing risk, or treating an individual in need thereof.

A method for treating or preventing vascular endothelial cell injured diseases, especially cerebral infarctions or myocardial infarctions, by administering a c-MET agonist antibody to a subject in need thereof, and specific c-MET agonist antibodies.

The present invention relates to binding fusion protein compositions comprising targeting moieties linked to extended recombinant polypeptide (XTEN), binding fusion protein-drug conjugate compositions, and XTEN-drug conjugate compositions, isolated nucleic acids encoding the compositions and vectors and host cells containing the same, and methods of using such compositions in treatment of diseases, disorders, and conditions.
