e.g. real-time PCR and analysis of transgenics or mutants Choose type of experiment common reference, e.g.: S1 x S1+T1, S1 x S1+T2 paired references, e.g.: S1 x S1+T1, S2 x S2+T1 loop & pooling designs many other designs At least three (two) biological replicates are essential Biological replicates: utilize independently collected biosamples
