  • Patent number: 6203976
    Abstract: The present invention provides a method of transcriptionally modulating the expression of a gene encoding a protein of interest, the expression of which gene is associated with the production in cell culture of a protein encoded by the gene, which comprises contacting a cell, which is capable of expressing the gene, with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell in culture, which molecule (a) does not naturally occur in the cell and (b) directly transcriptionally modulates expression of the gene.
    Type: Grant
    Filed: June 7, 1994
    Date of Patent: March 20, 2001
    Assignee: OSI Pharmaceuticals, Inc.
    Inventors: J. Gordon Foulkes, Franz E. Leichtfried, Christian Pieler, John R. Stephenson

  • Patent number: 5525512
    Abstract: An incubator includes a housing (1) and a set (2) of shelves (3) for sample containers (8) containing cell cultures, for instance, positioned therein. In order to make it possible to use the incubator together with a robotic manipulator or similar device, the shelves (3) are fitted with guide elements (4) for the sample containers (8), the guide elements defining the relative positions of the sample containers. A door (6) in the front of the incubator permits access by a robotic manipulator. When the door (6) in the front of the incubator is closed, a door (6) in the rear of the incubator permits access to the inside of the incubator by operating personnel.
