  • Publication number: 20130142734
    Abstract: Targeting of imaging probes specifically to diseased tissues such as cancer is attractive because it potentially allows the improvement of tumor detection. One of the problems associated with conventional, low molecular weight imaging probes is the limited tumor:background ratio. To circumvent this, imaging probes may be conjugated to polymeric carriers to target solid tumors by either passive accumulation of macromolecules into tumor tissues due to the “enhanced permeability and retention” effect (EPR effect) or active targeting through the incorporation of cell-specific recognition ligands that mediate binding to cancer-specific antigens. This invention describes an innovative targeting strategy for the selective delivery of diagnostic agents into solid tumors by means of polymer-NIR fluorochrome conjugates modified with targeting ligands that bind to antigens or receptors that are uniquely expressed or over-expressed on the target cells relative to normal tissues.

    Abstract: The present invention provides chromatography methods for removing a virucidal agent from a target protein such as an antibody. The method uses a hydrophobic, negatively charged mixed mode support that has high affinity for both the target protein and the virucidal agent. The method provides conditions that favor dissociation of the virucidal agent from the protein, allowing the virucidal agent to bind strongly to the support. The target protein is then eluted from the support under conditions such that the virucidal agent remains bound to the support.

    Abstract: The present invention is directed to a multimeric agent and a multimeric conjugate formed from this multimeric agent and a biologically active agent. Said multimeric conjugates have a longer life time in vivo and an increased avidity compared to the unmodified biologically agent. The present invention is further directed to a pharmaceutical or diagnostic composition containing said conjugate as well as to a method of its production. The invention additionally provides the use of said conjugates for the detection, determination, separation and/or isolation of a specific binding partner and for the diagnosis, prophylaxis and treatment of diseases in which the specific binding partner is directly or indirectly involved.
