Figure 2From: Efficiency clustering for low-density microarrays and its application to QPCRShown is an example of the experimental data that serve as input for further calculation. The logarithm (log2) of the initial concentration is shown on the horizontal axis and the C T values on the vertical axis. C T values are measured at initial dilution levels 1, 0.1, 0.01 and 0.001 and exhibit a strong linear trend.Back to article page
