Disclosed is a novel means for accurate qualitative and quantitative analyses for each N-glycosylation site. The method of analyzing N-linked sugar chain(s) of glycoprotein according to the present invention comprises: treating a part of a glycopeptide-containing sample to be analyzed with endo-β-N-acetylglucosaminidases to cleave off sugar chains while leaving one GlcNAc of the chitobiose core on the Asn at the N-glycosylation site; subjecting the obtained sugar chain-cleaved sample to preliminary liquid chromatography/mass spectrometry; predicting the retention time of the glycopeptide of interest and the mass-to-charge ratio (m/z) of the precursor ion in main analysis based on the results of the preliminary liquid chromatography/mass spectrometry; and carrying out the main analysis. By this method, the binding sites and structures of N-linked sugar chains in a glycoprotein can be analyzed. By using the sugar chain-cleaved sample as an internal standard in the main analysis, quantitative analysis of sugar chains at each glycosylation site also becomes possible.

The present invention, in the field of bioengineering and biotechnology, relates to a method for preparing a recombinant antibody with a unique glycan profile produced by a genome-edited CHO host cell. Specifically, according to a method of the present invention, the TALEN technology is used to edit the FUT8 gene in CHO cells that have been adapted for serum-free suspension growth. The edited CHO host cells can produce recombinant antibodies with a unique glycan profile. The unique glycan profile can be characterized by non-fucosylated N-linked oligosaccharide chains of the antibodies, extremely low N-glycosylation heterogeneity and uniform carbohydrate chains. The antibody prepared by the method of the invention exhibit significantly increased ADCC and greater stability.

The present invention relates to compounds, compositions, and methods are provided for covalently linking a cargo molecule, such as a therapeutic or a diagnostic agent, to a glycan in the Fab region of an antibody. Also provided are methods of modeling and producing antibodies having de novo Fab glycosylation sites. Also provided are antibody carrier conjugates, methods of using the conjugates.

Provided are antibodies and antigen-binding fragments thereof that bind specifically to human complement factor C2 and are capable of inhibiting activation of the classical and lectin pathways of the complement system. The antibodies and antigen-binding fragment exhibit improved manufacturability, pharmacokinetics, and antigen sweeping. Also provided are pharmaceutical compositions comprising the antibodies and antigen-binding fragments, nucleic acids and vectors encoding the antibodies and antigen-binding fragments, host cells comprising the nucleic acids or vectors, and methods of making and using the antibodies and antigen-binding fragments. The antibodies and antigen-binding fragments can be used to inhibit the classical pathway of complement activation in a subject, e.g., a human. The antibodies and antigen-binding fragments can also be used to inhibit the lectin pathway of complement activation in a subject, e.g., a human.

Provided herein are anti-TREM2 antibodies and related methods of making and using anti-TREM2 antibodies. Also provided are methods and compositions for enhancing an immune response and/or for the treatment of an immune-related condition in an individual, e.g., cancer, comprising killing, disabling, or depleting non-stimulatory myeloid cells using an anti-TREM2 antibody or antigen binding fragment thereof.

Compositions and methods are described for the delivery of a fully human post-translationally modified (HuPTM) monoclonal antibody (“mAb”) or the antigen-binding fragment of a mAb against human vascular endothelial growth factor (“hVEGF”)—such as, e.g., a fully human-glycosylated (HuGly) anti-hVEGF antigen-binding fragment—to the retina/vitreal humour in the eye(s) of human subjects diagnosed with ocular diseases caused by increased neovascularization, for example, neovascular age-related macular degeneration (“nAMD”), also known as “wet” age-related macular degeneration (“WAMD”), age-related macular degeneration (“AMD”), and diabetic retinopathy.

The invention described herein provides compositions comprising anti-PD-1 antibodies and related methods for treating cancer and other disorders responsive to PD-1 antagonism.

The present disclosure provides anti-FGFR2b antibodies or antigen-binding fragments thereof, isolated polynucleotides encoding the same, pharmaceutical compositions comprising the same, and the uses thereof.

The present invention is directed to regimens for administering one or more Antibody-Based Molecules that bind PD-1 or PD-L1, and LAG-3 (e.g, a PD-1×LAG-3 bispecific molecule) alone, or in combination with an Antibody-Based Molecule that binds a Tumor Antigen (TA) for the treatment of cancer. The invention particularly concerns the use of such regimens in conjunction with PD-1×LAG-3 bispecific molecules. The invention is directed to the use of such molecules, and to the use of pharmaceutical compositions and pharmaceutical kits that contain such molecules and that facilitate the use of such dosing regimens in the treatment of cancer.
