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.
