  • Patent number: 10962534
    Abstract: The invention relates to a method for the immobilization of biomolecules containing at least one sulfhydryl group, which method comprises contacting a modified metal surface with the biomolecule irradiating the resulting surface with UV radiation in the presence of a photo-initiator, wherein said metal surface is modified with a cross-linker compound comprising a terminal thiol or dithiol group covalently linked to the metal surface, a spacer group, which at the other terminal end is carrying an isolated double or triple bond.
    Type: Grant
    Filed: February 17, 2017
    Date of Patent: March 30, 2021
    Assignee: BOEHRINGER INGELHEIM VETMEDICA GMBH

  • Patent number: 8426357
    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.
