RNA quality of microdissected prostate cancer tissue stained with cresyl violet or haematoxylin. Consecutive slides from the same patient were stained with either cresyl violet (CV) or haematoxylin (HT), and matching tumor regions were isolated through LCM using whole tissue as control. While RIN values of microdissected tissues stained for cresyl violet or haematoxylin were similar (a), the morphology of cresyl violet stained slides was significantly more detailed than haematoxylin stained slides (b). Symbols represent material from the same patient. Median RIN values are shown, whiskers indicate interquartile range
