Webhigher the Ct (30-35), the less the mRNA detected is present, because you need more cycles of amplification to detect the fluorescence. If the Ct has a small value (10-15), the gene is highly expressed. Endogenous controls typically have a smaller Ct then regular genes. Delta Ct = Ct gene test – Ct endogenous control Delta Delta Ct = ∆Ct ...

WebApr 16, 2024 · A reported 20Ct for the most sensitive protocol implies a relatively less transmissible 1,000 to 10,000 (103-104) copies/ml in the sample, while an apparently identical 20Ct for the least sensitive protocol means a highly infectious 10,000,000,000 (1010) copies/ml in the sample. At 100,000 (105) viral copies/ml Ct counts vary from … WebWhen running qPCR experiments, what is the difference between quantification cycle (Cq) and threshold cycle (Ct)?
