The present invention is directed to a new composition for performing a nucleic acid amplification reaction comprising (i) a thermostable DNA-Polymerase, (ii) a thermostable 3′-5′ Exonuclease, and (iii) at least one primer for nucleic acid amplification with a modified 3′ terminal residue which is not elongated by said thermostable DNA-Polymerase as well as methods for performing a PCR reaction using this composition. Furthermore, the method is directed to kits comprising such a composition.
摘要:
The present invention concerns a labelling reagent in which the label is bound via an amide bond and a linker to a residue of the molecule which is essentially characterized in that the N atom of the amide bond and the label are linked together directly by a covalent bond. In particular these are phosphoramidites or reactive supports suitable for nucleic acid synthesis. The invention also concerns processes for the production of such supports from suitable precursors.
摘要:
In one form, a diagnostic element for determining at least one analyte is provided. In a further form, an analytical measuring device includes the diagnostic element. Still, other forms are related to methods for the determination of an analyte, correcting a signal generated by an analyte, and/or checking the detection optics of an analytical measuring device using the diagnostic element. Another form is related to a system for the controlled release of a reagent and the use of such a system as a circuit element. Other aspects include, but are not limited to, unique methods, techniques, products, systems and devices involving diagnostic elements.
摘要:
The present invention is directed to method for analyzing multiple nucleic acid molecules of interest comprising in the steps of (i) providing a plurality of beads, characterized in that each bead comprises at least two sequence specific amplification primers, further characterized in that at least one of the primers is bound to the bead via a cleavable linker, (ii) capturing the nucleic acid molecules of interest from a sample, (iii) clonally isolating the plurality of beads, (iv) cleaving the at least one primer, (v) clonally amplifying the nucleic acid thereby creating multiple amplification products, and (vi) analyzing the amplification products.
摘要:
An integrated instrument for oligonucleotide synthesis and PCR, and a system and method thereof are disclosed. The integrated instrument is basically composed of two independent modules. The first module is a unit for chemical de novo synthesis of oligonucleotides such as oligonucleotide primers and/or oligonucleotide hybridization probes. The second module is a unit for performing an analytical polymerase chain reaction amplification in real time, i.e. a qPCR. The two modules are operatively linked to each other in such a way that a user can load a nucleic sample to be analyzed into the integrated instrument and perform a PCR reaction by programming the instrument without a previous external synthesis of oligonucleotide amplification primers.
摘要:
The disclosure concerns the enzymatic synthesis of stable analogues of nicotinamide adenine dinucleotide NAD/NADH and nicotinamide adenine dinucleotide phosphate NADP/NADPH, the so-called “carba-NADs”, i.e. analogues of NAD/NADH or NADP/NADPH, respectively, comprising a carbacyclic sugar instead of ribose.
摘要:
Described are modified mononucleotides and processes for their production. The nucleotides have a structure in which B is a purine or pyrimidine, S is a sugar unit, Y is an OH, a monophosphate, or a diphosphate, and Acc is an electron acceptor selected from the group consisting of (a) —CN and (b) —SO2—R′ in which R′ contains one amino-substituted alkyl or one optionally substituted aryl.
