Abstract: The present invention relates to the production of proteins in host cells, and more particularly to host cells containing multiple integrated copies of an integrating vector comprising an exogenous gene and an amplifiable marker. The present invention further relates to the use of integrating vectors comprising an amplifiable marker. The present invention further provides methods of expressing increased levels of protein in host cells using such vectors.

Abstract: The present invention relates to the production of proteins in host cells, and more particularly to host cells containing multiple integrated copies of an integrating vector. Suitable integrating vectors for use in the present invention include retrovirus vectors, lentivirus vectors, transposon vectors, and adeno-associated virus vectors. Methods are provided in which the host cells are prepared by using the integrating vectors at a high multiplicity of infection. The host cells are useful for producing pharmaceutical proteins, variants of proteins for use in screening assays, and for direct use in high throughput screening.

Abstract: The present invention provides novel antibodies. In particular, the present invention provides fusion antibodies comprising antibody heavy and light chain fusions. The present invention further provides multivalent antibodies comprising multiple fusion antibody chains. The present invention further provides methods of generating splice resistant antibody genes.

Abstract: The present invention provides novel regulatory elements and vectors for the expression of one or more proteins in a host cell. The present invention also provides methods for expressing one or more proteins, such as antibodies, in a host cell. These methods utilize the novel regulatory elements and vectors of the present invention for the expression of proteins in a host cell. The host cells are used for producing various protein products, including but not limited to pharmaceutical proteins, antibodies, variants of proteins for use in screening assays, and for direct use in high throughput screening.

Abstract: The present invention provides methods for the production of a transgenic bovine. In particular, the present invention provides methods for generating transgenic bovines with transgenes that enhance the ability of the bovines to metabolize lipids. The present invention thus provides bovines resistant to fatty liver disease. The compositions and methods of the present invention provide a solution to costly disease.
