    摘要: Disclosed herein are compositions and methods for increasing the longevity of a cell culture and permitting the increased production of proteins, preferably recombinant proteins, such as antibodies, peptides, enzymes, growth factors, interleukins, interferons, hormones, and vaccines. By transfecting cells in culture with an apoptosis-inhibiting gene or vector, cells in culture can survive longer, resulting in extension of the state and yield of protein biosynthesis. Expression of the apoptosis-inhibitor within the cells, because it does not kill the cells, allows the cells, or an increased fraction thereof, to be maintained in culture for longer periods. This invention then allows for controlled, enhanced protein production of cell lines for commercial and research uses, particularly the enhanced production of growth factors, interferons, interleukins, hormones, enzymes, and monoclonal antibodies, and the like. The method preferentially involves eukaryotic cells in culture, and more advantageously mammalian cells in culture.

    摘要: Humanized, chimeric and human anti-CD20 antibodies and CD20 antibody fusion proteins that bind to a human B cell marker, referred to as CD20, which are useful for the treatment and diagnosis of B-cell disorders, such as B-cell malignancies and autoimmune diseases, and methods of treatment and diagnosis are disclosed. Methods of making the humanized, chimeric and human anti-CD20 antibodies are disclosed. A humanized anti-HSG (histamine-succinyl-glycyl) monoclonal antibody designated h679 which binds with high affinity to molecules containing the moiety histamine-succinyl-glycyl (HSG), and methods of making the humanized anti-HSG antibody also are disclosed.

    摘要: The invention provides for a polyvalent protein complex (PPC) comprising two polypeptide chains generally arranged laterally to one another. Each polypeptide chain typically comprises 3 or 4 “v-regions”, which comprise amino acid sequences capable of forming an antigen binding site when matched with a corresponding v-region on the opposite polypeptide chain. Up to about 6 “v-regions” can be used on each polypeptide chain. The v-regions of each polypeptide chain are connected linearly to one another and may be connected by interspersed linking regions. When arranged in the form of the PPC, the v-regions on each polypeptide chain form individual antigen binding sites.
