3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Ct value of the cycle threshold
Inflection corresponding to the real-time PCR cycles when the fluorescent signal from the background into the exponential growth phase.
3.2
Amplification curve amplificationcurve
In real-time PCR reaction, the template is amplified, real-time PCR product was subjected to linear growth, exponential growth phase
And the platform of the three stages, the amount of real-time fluorescence quantitative PCR product changes with time and the curve obtained.
4 technical principles
This experiment was conserved and specific primers were designed to explore the use of Songjiang perch and cytochrome b (Cytochromeb, Cytb) gene
Needle, establish real-time PCR method. The method is based on the conventional PCR, to add a specific fluorescent probe. Probe
For the period of oligonucleotides, both ends of the report marks a fluorophore and a quencher fluorophore. The probe is intact, the reporter group launched
The fluorescent signal is quenched group absorption; real-time quantitative PCR amplification, Taq polymerase 5'-3 'exonuclease activity of the enzyme degradation of the probe, so that
Report fluorophore and quencher fluorophore separate, thus fluorescence monitoring system can receive the fluorescent signal, that is, each strand of DNA amplification,
There is a fluorescent molecule is formed to achieve the formation and accumulation of PCR product fluorescent signal completely synchronized. This method has the real-time, quantitative,
Specificity, high sensitivity advantages.
