Table 6 Inter-experimental reproducibility of the quantification of a range of TGF-β1 and β2-MG RNA standards A set of TGF-β1 and β2-MG RNA standards ranging from 10³ to 10¹⁰ copies was amplified by RT-PCR. Coefficients of inter-experimental variation were determined from eight different experiments and calculated for threshold cycles.
