RNA integrity over time. In the tonsil samples, the ratios of the ribosomal peaks (28S/18S) were calculated based on the electropherograms. RNA was extracted from four samples (two samples with Trizol and two with the Qiagen-Kit). Values represent the mean and standard deviation of these four analyses.
