Fold-change difference

WebThus, the calibrator becomes the 1× sample, and all other quantities are expressed as an n-fold difference relative to the calibrator. This method compares the Ct value of one target gene to another (using the formula: 2 ΔΔCT)—for example, an internal control or reference gene (e.g., housekeeping gene)—in a single sample. AdvantagesWebNov 8, 2024 · Fold change is a measure describing how much a quantity changes going from an initial to a final value. For example, an initial value of 30 and a final value of 60 corresponds to a fold change...
