  1. A ANOVA coupled t-test was performed to determine which dilutions are statistically different from one another. The comparison of adjacent dilutions are shown. A p-value higher than 0.05 indicate that the model is unable to discriminate between the two adjacent dilutions. N/A stands for not available and indicate that the expected higher concentration of the comparison was in fact calculated to be lower from the qPCR results.
