Relative quantification

Three general procedures of calculation of the relative quantification ratio are established: 1 The so-called ‘delta C t’ (eqs 1–2 using ?C P) or ‘delta-delta C t’ method (eqs 3–4 using ??C P) without efficiency correction Here an optimal doubling of the target DNA during each performed real-time PCR cycle

Analyzing your QRT

The ??CT is calculated by: ??CT = ?CT test sample – ?CT calibrator sample For example subtracting the ?CT of the untreated from the ?CT of Drug Treatment A yields a value of –2 5 ??CT = 4 37 – 6 86 = –2 5 Calculate the standard deviation of the ??CT value The calculation of ??CT involves subtraction of the ?CT calibrator value

What is a Delta-Delta CT Method?

This is to essentially normalise the gene of interest to a gene which is not affected by your experiment, hence the housekeeping gene-term. To use the delta-delta Ct method, you require Ct values for your gene of interest and your housekeeping gene for both the treated and untreated samples.

What is Delta CT SD & RQ?

Delta Ct SD = Standard Deviation The standard deviation is calculated by the software with the delta Ct value of the technical triplicates. The triplicates are valid when the SD is smaller than 0.25. If the SD is over 0.25, the RQ value is considered unreliable. RQ = Relative quantification = 2-??Ct

What if cDNA dilution versus Delta CT is close to zero?

If the plot of cDNA dilution versus delta Ct is close to zero, it implies that the efficiencies of the target and housekeeping genes are very similar. If a housekeeping gene cannot be found whose amplification efficiency is similar to the target, then the standard curve method is preferred.

Is Delta-Delta CT the same as Pfaffl equation?

Many thanks for your message. The delta-delta Ct method assumes your primer efficiencies between your target gene and housekeeping gene are the same (or roughtly the same). However, what would be even better in your case is to use the Pfaffl equation to account for the slight differences in primer efficiencies.
