Experimental Variability and Replicates in siRNA Experiments

WebJun 11, 2024 · The assessment of time points (Figure 1B) and tissue sub sections (Figure 1C) coupled with the selection of an appropriate number of biological replicates per treatment group are good examples of key design parameters that are essential considerations to assure publication of precise, accurate, and reproducible data. Fig. 1. WebThe greater the fold changes between the means, the fewer biological replicates are needed. The more dispersed the population variability, the more biological replicates are needed. Figure 2 gives an estimate of the sample numbers needed, depending on the experimental precision and expected biological difference.
