6. Perform data analysis according to the following guidelines:

RNA control: Plot the Cq values for the RNA control against the percentage input
lysate (Figures 2A and 2B). A constant Cq value across the input lysate range
indicates no RT-qPCR inhibition. A deviation of >1 Cq value indicates RT-qPCR
inhibition. In the example shown in Figure 2A, optimal performance can be
achieved with 100,000–10 input cells

Target gene: If a target gene is amplified in parallel with the RNA control, plot the
Cq values for the target gene against the percentage input lysate (Figures 2A and
2B). A decrease in Cq value is expected as input lysate increases. Deviation in
the linear response of the RNA control results from incomplete lysis and/or from
RT-qPCR inhibition
