RNA quality check. RNA electropherograms obtained by running 250 ng of total RNA from aliquots of two representative samples on a 2100 Bioanalyzer with the RNA 6000 Nano LabChip. Elapsed time between surgical removal and freezing in liquid nitrogen is reported along with the RIN value. Each electropherogram reports fluorescence units as a function of running seconds.
