摘要:
A method and reagent for detecting the presence or amount of an analyte by a redox reaction and a fluorimetric determination, is disclosed. The reagent comprises a compound of the general formula Q-F as a redox indicator, wherein Q is a quencher group and F is a fluorophore group. The quencher group Q or/and the fluorophore group F can be reduced or oxidized, and the fluorescence can change depending on the reduction or oxidation.

摘要:
The present invention concerns new fluorescent dye systems especially for fluorescence resonance energy transfer determinations for example combined with the time-resolved measurement of the resulting fluorescence. The invention also concerns the use of these dyes to label biomolecules and for the homogeneous determination of interactions between biomolecules, for example for detecting an analyte.
摘要:
A method is disclosed for obtaining and/or immunologically detecting an analyte contained in a gas phase by immunologically binding the analyte to a binding partner thereof contained in a gas- and liquid-permeable first carrier matrix. Said method is characterized in that a) the analyte-containing gas phase is brought into contact with the first carrier matrix (immune adsorber), b) the analyte is bound to the first binding partner which is contained in the first matrix and not bound to the matrix, and c) the complex of analyte and first binding partner and the free first binding partner are eluted from the first matrix, d) the eluted complex or the free first binding partner is determined as a measure for the amount of analyte present.
摘要:
The invention relates to novel monomeric building blocks for labeling peptide nucleic acids and similarly constructed nucleic acid-binding oligomers possessing groups which are coupled to a nitrogen base and/or to the peptide backbone of the peptide nucleic acid. The invention furthermore relates to peptide nucleic acids which contain at least one labelled monomeric building block.
摘要:
Compounds of the general formula Ia and Ib are described ##STR1## in which R.sup.1 and R.sup.2 are the same or different and represent hydrogen, straight-chain or branched C.sub.1 to C.sub.6 lower alkyl or an aryl group optionally substituted by electron-withdrawing groups, R.sup.3 denotes a cleavable group, W is hydrogen, halogen or a pseudohalogen and at least one of the groups R.sup.4 or R.sup.5 is a group stabilizing the dioxetane structure and at most one of the groups R.sup.4 or R.sup.5 represents hydrogen and X or Y represents oxygen, N-R or C(R).sub.2 in which R has the meanings stated for R.sup.1 and R.sup.2 or represents a mesomeric double bond or a carbonyl group and n denotes the number 0 or 1 and m denotes the number 1 or 2, as well as a process for their production. These compounds are new and can be used as substrates in immunological assays and in DNA diagnostics using activating agents for colour formation.
