In particular, the present invention relates to the monoclonal antibody, which can bind PCSK9 specifically, block association of PCSK9 with LDLR, upregulate the amount of LDLR on cell surface, heighten the metabolism of LDL cholesterol and/or triglycerides, and prevent/treat cardiovascular diseases caused by hypercholesterolemia.
Abstract: The application discloses an anti-Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) monoclonal antibody, an amino acid sequence comprising coded antibody variable regions and Complementarity-Determining Regions (CDR), the obtaining method, and application of monoclonal antibody. The anti-PCSK9 monoclonal antibodies are screened from a phage antibody library; affinity maturation is achieved by using a method that the phage antibody library is established by means of chain displacement; After screening the light chain CDR1, 2, 3 Mutant Library of monoclonal antibodies obtained from primary screening; monoclonal antibodies having high affinity are selected; then screening the mutant libraries of heavy chain CDR1, 2, 3 regions; and finally the monoclonal antibodies having high affinity are screened.

Abstract: The present invention relates to a humanized anti-CD20 antibody that comprises an antigen binding site containing heavy and light chain of obinutuzumab (GAZYVA®), and N-linked oligosaccharides that are attached to the Fc region of the antibody, wherein the N-linked oligosaccharides are not bisected by N-acetylglucosamine. The antibody of the present invention comprises fucose glycotype in an amount of no more than 10% of the total N-glycans that are attached to the Fc region of the antibody. The anti-CD20 of the present invention has antibody dependent cell-mediated cytotoxicity (ADCC) about 2 times stronger than that of GAZYVA® and about 50 to 100 times stronger than that of RITUXAN®. The anti-CD20 antibodies are effective for treating CD20 expressing cancer, such as non-Hodgkin's lymphoma, B cell lymphoma, chronic lymphocytic leukemia, or follicular lymphoma.
