Where:

E = Efficiency of primer and probe set. This efficiency is calculated with the formula
(% Efficiency * 0.01) + 1, where 100% efficiency = 2

Standard Deviation of Relative Quantity

The standard deviation of the relative quantity is calculated with the following formula:

Where:

SD Relative Quantity = standard deviation of the relative quantity

SD C

q

sample = Standard deviation of the C

q

for the sample (GOI)

Relative Quantity = Relative quantity of the sample

E = Efficiency of primer and probe set. This efficiency is calculated with the formula
(% Efficiency * 0.01) + 1, where 100% efficiency = 2

GOI = Gene of interest (one target)

Efficiency Corrected Cq (Cq

E

)

The efficiency corrected Cq is calculated by the following formula:

Where:

E = Efficiency

Mean Efficiency Corrected Cq (MCq
