Clustering of samples with similar levels of RNA degradation evident in results from both IVT and DASL assays. Average hierarchical clustering was applied to the Euclidean distance between intact and artificially degraded brain and pooled reference RNA samples. Thus the more degraded the sample is regardless of assay, the less similar it is to the intact sample. Labels indicate assay type and time of degradation. B0 = intact reference brain RNA; B10 = 10 minute heating at 95°C; B30 = 30 minute heating at 95°C; B60 = 60 minute heating at 95°C; P0 = intact reference pooled RNA; P10 = 10 minute heating at 95°C; P30 = 30 minute heating at 95°C; P60 = 60 minute heating at 95°C; B75P25 = 75% brain reference RNA and 25% pooled reference RNA combination; B25P75 = 25% brain reference RNA and 75% pooled reference RNA combination; rep = technical replicates.
