I am quantifying relative amounts of different genomic variants in a population of cells. Basically, in a population, a certain percentage will be in state "A" and the remaining percentage in state "B". I have optimised qPCR primers to detect both states with equivalent amplification efficiencies.
For that, I extract genomic DNA from the whole populatio and then qPCR for state "A" and "B" separetly as well as another region that is stable (calibrator or reference for gDNA input). I can calculate the fold change in between these two states by deltadeltaCt.
However, I would like to express the fold change in relative percentage, so instead of reporting 0.4 of fold change of state "A" versus state "B", I would like to say that state "A" exist in X% in the population. Anyone has an idea how to do that? It should be similar to what folks working with siRNA have been doing, as is calculating % of knockdown of specific gene.
