  • Patent number: 8853132
    Abstract: 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.

  • Patent number: 8357490
    Abstract: 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.
