Figure 1From: Reliable detection of Bacillus anthracis, Francisella tularensis and Yersinia pestis by using multiplex qPCR including internal controls for nucleic acid extraction and amplificationEffect of increasing concentration differences between targets in multiplex qPCR reactions. Dilution series of multicopy targets (A-C) or internal control target cry1(D-F) were made in the presence of the other targets detected in each qPCR at a constant concentration near the detection limit. Triplicate multiplex qPCR measurements were performed and mean Cq values with 95% confidence limits are shown for each target.Back to article page
