Can I arbitrarily take a cycle number of 40 for the gene that was not expressed at all in qPCR results calculation?

I ran RT-qPCR for a control and a treated group and it appears that my gene of interest was not expressed at all in any of the subjects in the control group. So I was wondering if I could...

Does anyone know if the Quantstudio 3 qPCR machine requires a passive reference when Using SYBR? I ran a qPCR and got the plot in the attached file.?

I know that my target is in my sample as I extracted it from cell culture myself. These plots show some amplification. The first one seems O.K for the first 36 cycles but then collapses at the...

Having trouble with qPCR amplification plots. My curve's never seem to reach a plateau. Any ideas?

The parameters of the curve all seem acceptable, typically reactions results are above 0.9852, -3.1 to -3.6 slope, and 90-110% reaction efficiency. The results seem to be what I would expect from...
