Fluorescent probes are an oligonucleotide with a fluorescent label and a suppressor that can bind to the DNA chain during amplification. When the probe is in a free state, both dyes are located close to each other, therefore, fluorescence quenching occurs. During PCR, at the stage of chain elongation, the hybridized probe is cleaved by a polymerase that has 5’-exonuclease activity, the dyes are separated, and a fluorescent signal proportional to the amount of the amplified product is observed. The fluorescence intensity increases in each cycle in proportion to the probe splitting rate. The use of probes in PCR makes it possible to increase the accuracy and selectivity of the reaction. A wide range of fluorescent dyes: FAM, R6G, VIC, HEX, JOE, TAMRA, ROX, Cy 5 and Cy5.5 The possibility of multiplex analysis of multiple DNA targets in one test tube. High efficiency of PCR-RV. Probe quality control: HPLC purification and mass spectrometry verification

Oligonucleotides are short fragments of nucleic acids that are widely used in various fields of DNA diagnostics (medical diagnostics, forensic analysis, veterinary medicine, food quality control, etc.). Recently, oligonucleotides have been widely used as medicines against various genetic and other diseases. GenTerra produces DNA and RNA oligonucleotides on a scale of several milligrams to gram quantities, including modified oligonuleotides, fluorescently labeled oligonucleotides and real-time PCR probes.

The dNTP mixture is an aqueous solution of four highly purified 2’-deoxynucleoside-5’-triphosphates (dATP, dTTP, dHTF, dCTF) in equimolar concentration
