Abstract: The properties of an Fc-containing protein, for example, an antibody, are controlled by altering the sialylation of the oligosaccharides in the Fc region by transfecting the cell line expressing the Fc-containing protein with a vector sequence encoding a sialidase. The modified Fc-containing proteins have therapeutic utility in diseases or conditions in which it is desirable to control the affinity for one or more of the Fc?RI, Fc?RIIA, and Fc?RIIIA receptors, ADCC activity, macrophage or monocyte activation, serum half-life, and avidity.

Abstract: The present invention relates to anti-TNF antibodies comprising all of the heavy chain variable CDR regions of SEQ ID NOS:1, 2 and 3 and/or all of the light chain variable CDR regions of SEQ ID NOS:4, 5 and 6, specific for at least one human tumor necrosis factor alpha (TNF) protein or fragment thereof, as well as nucleic acids encoding such anti-TNF antibodies, complementary nucleic acids, vectors, host cells, production methods and therapeutic methods.

Abstract: Antibody expression vectors and plasmids can incorporate various antibody gene portions for transcription of the antibody DNA and expression of the antibody in an appropriate host cell. The expression vectors and plasmids have restriction enzyme sites that facilitate ligation of antibody-encoding DNA into the vectors. The vectors incorporate enhancer and promoter sequences that can be varied to interact with transcription factors in the host cell and thereby control transcription of the antibody-encoding DNA. A kit can incorporate these vectors and plasmids.

Abstract: An anti-IL-12 antibody that binds to a portion of the IL-12 protein corresponding to at least one amino acid residue selected from the group consisting of residues 15, 17-21, 23, 40-43, 45-47, 54-56 and 58-62 of the amino acid sequence of the p40 subunit of IL-12, including isolated nucleic acids that encode at least one anti-IL-12 antibody, vectors, host cells, transgenic animals or plants, and methods of making and using thereof have applications in treating IL-12-related disorders, such as psoriasis.

Abstract: Antibody and other Fc-containing molecules with glycosylation variations in the Fc region show increased resistance to proteases, such as pepsin, plasmin, trypsin, chymotrypsin, a matrix metalloproteinase, a serine endopeptidase, and a cysteine protease. The Fc-containing molecules are useful in the treatment of various diseases and disorders.

Abstract: Isolated anti-tissue factor antibodies, immunoglobulins, cleavage products and other specified portions and variants thereof having enhanced ADCC activity, as well as anti-tissue factor antibody compositions, encoding or complementary nucleic acids, vectors, host cells, compositions, formulations, devices, transgenic animals, transgenic plants, and methods of making and using thereof. The antibodies of the invention bind human tissue factor and demonstrate enhanced ADCC activity. Accordingly, the antibodies can be used in a variety of methods for diagnosing, treating, and/or preventing diseases involving tissue factor, where enhanced ADCC activity is desirable such as cancer.

Abstract: Antibody preparations with substantially homogeneous and unsialylated glycoforms, such as G0 and G2, are prepared by enzymatic treatment, expression under certain conditions, use of particular host cells, and contact with serum. These antibody preparations resist cleavage by proteases, such as papain, ficin, bromolein, pepsin, a matrix metalloproteinase, such as MMP-7, neutrophil elastase (HNE), stromelysin (MMP-3) and macrophage elastase (MMP-12), and glycosylation modification enzymes. The antibody preparations with substantially homogeneous and unsialylated glycoforms and methods of testing for glycosylation in an antibody are useful in connection with characterization of antibody properties and/or in diseases or conditions characterized by an increase in protease activity.
