    摘要: The invention relates to a ruthenium complex having the formulaRu.sup.2+ L.sub.1 L.sub.2 L.sub.3 Iwherein L.sub.1, L.sub.2 and L.sub.3 are the same or different are equal to a bi- or polycyclic ligand with at least two nitrogen-containing heterocycles, whereby at least one of these ligands is substituted with at least one group conferring water-solubility, and whereby at least one of these ligands is substituted, optionally via a spacer group, with at least one reactive group, and whereby the ligands L.sub.1, L.sub.2 and L.sub.3 are attached to the ruthenium via nitrogen atoms.The invention is further related to such ruthenium complexes having coupled thereto an immunologically active material, for example, antigens, haptens or antibodies and to the use of said ruthenium complexes in fluorescence spectroscopy. Specific ligands L.sub.1, L.sub.2 and L.sub.3 which are useful in the ruthenium complexes of the invention are, e.g., 2,2'-bipyridine, 1,10-phenanthroline benzbathophenanthroline or bathophenanthroline groups. Groups which are useful for conferring water-solubility on said ligand are, e.g. sulfonic acid groups which are preferably present in the form of their salts. Useful spacer groups are e.g. an alkylene groupcontaining 1-8 carbon atoms and which is optionally substituted with --SO.sub.2 --NH--, --S--, --O--, --COO-- or --CO--NH-- groups. Useful reactive groups to which the immunologically active material is coupled, are e.g. --COOH, --I, --NH.sub.2, --NCS or --SO.sub.2 Hal groups. The ruthenium complexes according to the present invention can be detected with great sensitivity by fluorescence spectroscopy and are thus useful in fluorescense immunoassays.

    摘要: The display comprises a cholesteric liquid crystal film in which are embedded dye molecules between the two walls separated by a shim. One wall is at least partly covered by a reflecting coating reversing the polarization of a circularly polarized electromagnetic wave. The optical anisotropy .DELTA.n and the helix pitch p are such that the least absorbed wave on passing through the cell has an ellipticity equal to or greater than .pi./8.

    摘要: 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.
