From: Biobanking of fresh frozen tissue: RNA is stable in nonfixed surgical specimens
RNA was purified from a number of different tissues of the local frozen tissue biobank (Department of Pathology, Uppsala University Hospital). Tissue type as indicated below each bar (SCC=squamous cell carcinoma, BCC=basal cell carcinoma). The RNA was extracted using Trizol and analysed with a Bioanalyzer. The ratios of both ribosomal peaks (28S/18S) were calculated based on the electropherograms. Only two samples failed to show ribosomal RNA peaks.
