摘要:
The current invention restates substituted nitroindole nucleosides as both terminal as well as internal building blocks of labeled oligonucleotide probes for the detection, analysis and quantitation of nucleic acids. The substituent comprises a linker and a detectable group or a linker and a reactive group for post synthesis coupling. These modified nucleosides grant access to a wide application area. These new substituted nitroindole nucleosides can be used as labeling reagents for the facile preparation of, e.g., optimized hybridization probes, simple probes, TAQMAN-probes or molecular beacon probes.

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:
A microphone amplifier comprises an input terminal (E100) for applying an input signal (IN), an output terminal (A100a) for outputting an output signal (OUT), and an additional output terminal (A100b) for outputting an additional output signal (VBIAS). The microphone amplifier also contains an amplifying circuit (10) for generating the output signal (OUT) by amplifying the input signal (IN), wherein the amplifying circuit (10) is connected between the input terminal (E100) and the output terminal (A100a), and a voltage generator (30) for generating the additional output signal (VBIAS). A supply voltage terminal (V30) of the voltage generator (30) is connected to the output terminal (A100a) of the microphone amplifier. Since the amplifying circuit (10) makes available a supply voltage (V) for the voltage generator (30), the microphone amplifier can be operated without a separate supply voltage terminal.
