    摘要: A mammalian cell gene expression vector system comprising (a) an episomal maintenance system (b), a strong promoter/enhancer, (c) a protein transactivation system and (d) DNA coding for a heterologous protein. The episomal maintenance and protein transactivation systems can include sub-elements located on the same or different plasmids within the cell expression system.

    摘要: This invention describes a protein-free production process for proteins having factor VIII procoagulant activity. The process includes the derivation of stable human cell clones with high productivity for B-domain deleted Factor VIII, and (2) the adaptation of cells to grow in a medium free of plasma-derived proteins.

    摘要: Human/human hybrid cells were made via fusion of human embryonic kidney cells (293S) and modified Burkitt's lymphoma cells (2B8). The fusion cells are useful as host cells for the recombinant expression of mammalian genes. The advantages of using these hybrid clones of human kidney- and B-cells, called HKBs, for mammalian gene expression, include (i) the cells are negative for immunoglobulin expression, (ii) the cells grow easily in plasma protein-free medium (with or without the addition of recombinant insulin) as suspension cultures in a shake flask or in a fermenter (iii) the cells are very susceptible for transfection of DNA, and (iv) the cells secrete high levels of heterologous recombinant proteins, such as recombinant monoclonal antibodies, soluble ICAM-1, rIL-4, and rFVIII.
