摘要:
The invention relates to compounds, which are useful for intramolecular fluorescence resonance energy transfer (FRET), comprising the oxidized form of a carbaNADH-based first fluorophore and a second fluorophore that is excitable at a wave-length of between 445 to 540 nm and that has an emission maximum of greater than 560 nm, and methods, kits and compositions related thereto.
摘要:
The trivalent phosphorous atom of a compound is reacted with a reagent in such a manner that a stable phosphate mimetic or a specifier is formed. Phosphoramidites with a phosphorous atom containing at least one hydroxyl residue which is provided with a protective group are reacted for this purpose with a free hydroxyl group: In the first synthesis cycle the hydroxyl group is linked to a solid support via a cleavable or non-cleavable linker. In further synthesis cycles the hydroxyl group is created by cleavage of the protective group from the growing oligomer. This results in formation of a phosphorous acid triester which is reacted with azides. By selecting suitable monomers for the synthesis which have a defined stereoconformation compounds of Formula (1) are produced in a stereocontrolled manner.
摘要:
The present invention is directed to Synthetic peptide having a length of not more than 30 amino acids comprising a divalent cation binding site. Such a peptide according to the present invention is part of a composition for nucleic acid amplification and provides for a so called hot start effect.
摘要:
The present invention relates to a chemical compound comprising a light emitting moiety precursor (eg. acridine, luciferine) and a precursor of a leaving group (eg. oxazine, anilide), bound to each other by an amide or by an ester bond and characterized in that the leaving group precursor upon oxidation is converted into the leaving group. The invention also relates to compounds additionally comprising a coupling group to the use of such compounds for labeling of biomolecules and more generally to the use of such compounds in chemiluminescence detection procedures.
