From: Applicability of RNA standards for evaluating RT-qPCR assays and platforms
Accuracy of fold change detection. Two panels (A and B) containing different ratios of RNA standards across a range of copy numbers were quantified using (A) cDNA with the ABI 7900HT system or (B) pre-amplified cDNA with BioMark 48 × 48 dynamic arrays. Expected fold change values (see the tables below the Figures) are compared to the mean of measured fold changes from RT-qPCR reactions performed on six pairs of samples. The error bars represent standard error.
