    摘要： The invention concerns rhodamine derivatives of the general formulae in which Ca-Cd each denote a C atom, and Ca and Cb as well as Cc and Cd are either linked together by a single bond or by a double bond; X1 to X16 denote independently of one another halogen, sulfonic acid, hydrogen or an alkyl residue with 1-20 C atoms in which the alkyl residue can be substituted with one or several halogen or sulfonic acid residues; R1 and R2 are either identical or different and denote either hydrogen, alkyl with 1-20 C atoms, polyoxyhydrocarbyl units, phenyl or phenylalkyl with 1-3 carbon atoms in the alkyl chain in which the alkyl and/or phenyl residues can be substituted by one or several hydroxy, halogen, sulfonic acid, amino, carboxy or alkoxycarbonyl groups where alkoxy can have 1-4 carbon atoms, R1 contains at least one activatable group, R2 and X4 can be optionally linked together via a bridge composed of 0-2 C atoms. In contrast to the prior art, these compounds are characterized in that A1, A2 and A3 can independently of one another denote hydrogen, cyano, halogen and sulfonic acid; B1 denotes either halogen, cyano or hydrogen; B2 denotes hydrogen, amide, halogen and an alkyl residue with 1-20 C atoms. In addition the invention concerns activated rhodamine derivatives, correspondingly conjugated biomolecules and their use in diagnostic systems.

    摘要： Compositions, reaction mixtures, and kits, as well as methods for their use, comprising a pair of FRET hybridization probes hybridizing adjacently to a target nucleic acid sequence, each hybridization probe comprising (i) a nucleotide sequence entity which is substantially complementary to the sequence of the target nucleic acid, (ii) a fluorescent entity, being either a FRET donor entity or a FRET acceptor entity, and (iii) a spacer entity connecting the nucleotide sequence entity and the fluorescent entity. The intensity of fluorescence emission from the FRET donor entity and from the FRET acceptor entity is not substantially affected by quenching activity of nucleotide residues present in the sequence of the target nucleic acid or in the nucleotide sequence entities of the hybridization probes.

    摘要： The present invention concerns a method for the quantification of a target nucleic acid in a sample comprising the following steps: (i) determination of the amplification efficiency of the target nucleic acid under defined amplification conditions, (ii) amplification of the target nucleic acid contained in the sample under the same defined reaction conditions, (iii) measuring the amplification in real-time, (iv) quantification of the original amount of target nucleic acid in the sample by correction of the original amount derived from step (iii) with the aid of the determined amplification efficiency. The efficiency correction of PCR reactions according to the invention for the quantification of nucleic acids can be used for absolute quantification with the aid of an external or internal standard as well as for relative quantification compared to the expression of housekeeping genes.
