  • Patent number: 5874533
    Abstract: Polypeptides which include at least one antigenic and/or immunogenic determinant of the envelope protein (env) of the HIV-2 virus and their production by recombinant DNA technology and the DNA sequences, expression vectors and transformed single-cell organisms used in this process are provided. A method for the detection of HIV antibodies or HIV viruses in human sera or in other biological fluids is also provided.
    Type: Grant
    Filed: March 15, 1994
    Date of Patent: February 23, 1999
    Assignee: Roche Diagnostic Systems, Inc.
    Inventors: Wilhelm Bannwarth, Patrick Caspers, Stuart Le Grice, Jan Mous
  • Patent number: 5811548
    Abstract: There are described compounds of the formula ##STR1## Wherein the variables have been defined herein. The compounds are useful as research tools in the determination of biologically active peptides sequences and also potentially suitable as medicaments, some of them being useful in the prevention or control of the formation of blood platelet thrombi, and some compounds are useful as intermediates.
    Type: Grant

  • Patent number: 5573906
    Abstract: A process for the detection of a nucleic acid sequence in a homogeneous assay format using an energy transfer system is disclosed. This process utilizes a 5' labeled primer containing a selfcomplementary sequence in an amplification or extension process together with a subsequent detection step using a 3' labeled probe for the amplified or extended region. The labels will be close together in space after hybridizing the probe close to the short piece of double-stranded DNA resulting from backfolding of the selfcomplementary region of the primer which has been incorporated into the amplified or extended product. A new primer for use in this process is also disclosed.

    Date of Patent: November 12, 1996
    Assignee: Hoffmann-La Roche Inc.
    Inventors: Wilhelm Bannwarth, Francis Muller
  • Patent number: 5278043
    Abstract: Energy-transfer systems which can be used, inter alia, for measuring distances within or between different molecules are described, comprising derivatives of lumazine and ruthenium, in particular derivatives of DNA or RNA sequences.
