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.

Anti-tissue factor antibodies and compositions

The present invention relates to the recombinant production of amphiphilic peptides with biologically and therapeutically significant activities. In one embodiment, this invention relates to recombinantly producing an amphiphilic peptide by providing a protease-deficient microbial host transformed with an expression vector containing DNA that encodes the amphiphilic peptide under the control of a regulatory sequence operable in the microbial host and expressing the amphiphilic peptide in the transformed microbial host. In another embodiment, this invention relates to providing an E. coli protease-deficient K-12 cell transformed with a vector that expresses a cleavable fusion protein comprising at least part of a carbohydrate binding protein and the amphiphilic peptide in the cell, expressing the fusion protein in the cell, and cleaving the fusion protein to obtain the amphiphilic peptide substantially free of carbohydrate binding protein residues. The biologically active amphiphilic peptide so produced can be further treated chemically or enzymatically to obtain a chemically distinct amphiphilic peptide with improved biological and therapeutic properties.
