RNA degradation in degraded frozen-tissue based RNA affects IVT greater than DASL processing. Boxplots show genome-wide intensity distribution of frozen brain-extracted RNA samples from four cases and replicates processed by IVT- and DASL-based assays. The IVT-processed samples clearly show distributions clustered at background intensities especially for samples with low RIN (2.2 for UMB4670 and 2.4 for UMB4721). The distribution of DASL-processed samples for UMB4670 and UMB4721 did not appear significantly different from samples with higher RIN (6.3 for UMB4849 and 4.9 for UMB1649). Rep = replicate.
