Dear collegues,
Does anybody know a publication stating the minimum theoretical (and practical) limit of detection for qPCR? We work with sensitive assays (about 0.2 ng/ul) that in our case corresponds to about 5-9 DNA copies. Now we prepare a manuscript, and I would want to mention in Discussion section any reference concerning a general limit of detection of the qPCR method. However, I still did not find any appropriate paper.
