Splet25. sep. 2012 · After condition optimization, a threshold value of S/N (fluorescent intensityafter/fluorescent intensitybefore) for positive reactions was defined for WSSV TaqMan probe-iiPCR on the basis of 20 blank reactions. WSSV TaqMan probe-iiPCR generated positive S/Ns from as low as 101copies of standard DNA and lightly infected … Splet23. apr. 2024 · DNA is a type of promising material for the construction of sensors owing to its sequence programmability to control the formation of certain structures. MicroRNA (miRNA) can be applied as promising biomarkers for the diagnosis of a range of diseases. Herein, a novel fluorescent sensing strategy for miRNA is proposed combining duplex …

Splet01. feb. 2009 · (A) In qRT-PCR, the fluorescence intensity is measured in real-time, allowing a CT to be defined for each cDNA sample. PCR for the target gene is shown by coloured lines and PCR for the reference gene by dotted lines. Each colour corresponds to a cDNA sample. C is the threshold, a constant fluorescence intensity, used to determine each CT. SpletFluorescence intensity and bacterial cell number had a linear relationship (Fig. 2), with a minimum detectable cell number of ∼5 × 10 5 cfu ml −1 for P. syringae and ∼5 × 10 4 cfu ml −1 for A....
