N: the total number of wells. Np: number of positive wells. Nn: number of negative wells. λ: copies per well = −ln(Nn/N) = Copies in the reaction/Total wells = Concentration in reaction (Copies/μL) × V (volume of each well). V = Reaction volume/N = 10.4 μL. P(0) = Nn/N = e^−λ, λ = −ln(Nn/N) = Concentration in reaction × V. Concentration in reaction = [−ln(N/N)]/V. Target RNA concentration = 10 × C_Copies/μL = 10⁴ × C_Copies/mL.
