  • Patent number: 5908790
    Abstract: The invention relates to monoclonal antibodies (mAB) which bind to water-soluble complexones such as ethylenediamine tetraacetate (EDTA) or diethylenetriamine pentaacetate (DTPA) with high specificity and avidity and retain their high avidity and specificity for these complexones after complexing of EDTA or DTPA with metal ions. These mAB can therefore be used, e.g. coupled on filters or other supports, for removing toxic heavy metals which are complexed with EDTA or DTPA. Furthermore, these mAB are suitable as components of immunoassays (RIA, ELISA etc.) for the quantitative determination of EDTA or DTPA in aqueous solutions.

  • Patent number: 5830880
    Abstract: A DNA sequence for the gene therapy of tumors is described. In its essential elements, the DNA sequence is composed of an activator sequence, a promoter module and a gene for the active substance. The activator sequence is activated, in a cell-specific manner, in proliferating endothelial cells or in cells which are adjacent to these endothelial cells. This activation is regulated by the promoter module in a cell cycle-specific manner. The active substance is an inhibitor of angiogenesis or a cytostatic or cytotoxic molecule. The DNA sequence is inserted into a viral or non-viral vector which is supplemented with a ligand which possesses affinity for the activated endothelial cell.
