  • Patent number: 7214532
    Abstract: The invention concerns human cells which, due to an activation of the endogenous human EPO gene, are able to produce EPO in an adequate quantity and purity to enable a cost-effective production of human EPO as a pharmaceutical preparation. Furthermore the invention concerns a process for the production of such human EPO-producing cells, DNA constructs for the activation of the endogenous EPO gene in human cells as well as a process for the large-scale production of EPO in human cells.

  • Publication number: 20040265855
    Abstract: The present invention relates to a method for screening a collection of nucleic acid molecules for a desired property of the nucleic acid or of a (poly)peptide encoded thereof, comprising the steps (a) automated picking of the cell collection containing the collection of nucleic acid molecules with a first robot; (b) automated lysis of the cells with a second robot; (c) automated separation of the cell DNA from the cell debris with a second robot; (d) optionally automated separation of endotoxins from the DNA with the second robot if the cells are bacteria; (e) automated transfection of the cells with the DNA obtained in step (c) or, if the cells are bacteria, with the DNA obtained in step (d) with a third robot; and (f) automated screening for the desired property with a fourth robot.

  • Patent number: 6025142
    Abstract: The invention relates to an antibody which inhibits the binding between u-PA and u-PAR to an extent of at least 90% in an assay as defined in the specification, or an active fragment or immunological equivalent of said antibody. Examples of such antibodies are deposited Jul. 7, 1994 at Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSM) with accession numbers DSM ACC2178 and DSM ACC2179 under the terms and conditions of the Budapest Treaty. The invention furthermore relates to a method for detecting or quantifying u-PAR or a glycosylation variant of u-PAR in a sample by use of an antibody according to the invention.Furthermore, the invention relates to a method for the manufacture of a therapeutic agent for preventing or counteracting localized proteolytic activity using of an antibody of the invention as well as to use of an antibody according to the invention for the preparation of a diagnostic agent which is capable of targeting a diagnostic to a cell that contains a u-PAR on the surface.
