  • Patent number: 7189515
    Abstract: The invention provides in vitro methods of detection using human antibodies. The methods are particularly useful for analyzing human samples containing HAMA or heterophilic antibodies. A human antibody can bind to an analyte in such samples without binding to HAMA or heterophilic antibodies present in the samples. The methods can be effected using a sandwich format among others.

  • Patent number: 7169572
    Abstract: Methods are disclosed for determining, in a sample derived from a human, the functional activity of a component of the human blood coagulation system, which activity can be correlated to conversion of a substrate specific for activated Protein C (APC), by measuring in an assay medium containing the sample and a substrate for APC, the conversion of the substrate by APC and correlating the conversion to the functional activity of the component. When the component is anticoagulant Factor V, at least one of exogenous APC, Protein S or an inhibitor of Protein S activity is added to the medium. When the component is Protein C, APC, or Protein S, exogenous anticoagulant Factor V or an inhibitor of anticoagulant activity of Factor V is added to the medium. Methods are also disclosed for diagnosing a blood coagulation/anticoagulation disorder or for determining a predisposition thereto in a human by determining anticoagulant Factor V activity in an assay medium containing a sample derived from the human.

  • Patent number: 7135302
    Abstract: The present invention relates to a method for predicting whether or not transplant recipients are likely to reject tissue allografts. It is based, at least in part, on the discovery that, based on analysis of three immunologic factors, cardiac transplant recipients could be classified into risk categories for progression to high-grade rejection. The present invention, by enabling a determination of the risk for high-risk rejection in a transplant patient, reduces unnecessary diagnostic and therapeutic procedures in low risk patients and clinical intervention in patients who would most benefit.

  • Patent number: 7105162
    Abstract: Pharmaceutical composition containing at least one peptide or protein (fragment) with an immunomodulatory activity together with an adjuvant. The peptide is derived from a pathogenic agent or a tumour antigen. The adjuvant is capable of increasing the binding of the peptide to the cells of the individual to be treated or of increasing the entry of the peptide into the cells and strengthening the immunomodulatory activity of the peptide. Preferred adjuvants are basic polyamino acids such as polyarginine or polylysine, optionally conjugated with a cellular ligand such as a carbohydrate group or transferrin. The composition is particularly intended for use as a vaccine, e.g. as a tumour vaccine.
