Web11 okt. 2024 · Fold change is ratio between values. Typically, the ratio is final-to-inital or treated-to-control *. Log2, or % are just representations of the ratio . Log2 in partcular, usually reduces the "dynamic range" of the ratios in a monotonic mapping. So rather than handling ratios between 1-1000, these map to about 0-10. WebTo calculate the relative gene expression values, simply divide the RQ of the GOI by the geometric mean of the RQ values for the reference genes (i.e. that created in the previous step).
