Figure 4.
Endpoint fluorescence values for DNA standards subjected to non-instrumented nucleic acid amplification with assimilating probe. Standards classified as positive (black circles) and negative (white circles) for amplification describe a best-fit logistic curve (a = 11380; b = −0.6413; x0 = 1009; R2 = 0.841, RMSE = 2130) resulting in a detection limit of 861 fg DNA (vertical solid line, equivalent to 137 copies of the R. solanacearum genome). A single genome copy equivalent is represented by the vertical dashed line.
