i am trying to do standard curves for a couple of primer pairs that i want to use for measuring the expression levels for a gene (MRNA) after mammalian cells transfection with a plasmid containing the cDNA of the gene of interest.
The standard template with known concentration that i have used for standard curves, is the original plasmid used for transfection with different serial dilutions. Is that correct??

I have performed two times and in every time i didn't get amplification plots in the qpcr, i feel that, it is not right to use plasmid DNA as a template for qPCR. Do you any idea about that?

also, can you add a pic of your melting curves?
