Improved stabilisation of human pancreas biopsies: Comparative evaluation of RNA preservation methods

Figure 3 Regional variation in RNA yield and integrity across the human pancreas. ^aAdjusted P value < 0.05. Bar plots showing the mean ± SD of the yield (ng/mg tissue) and integrity (RNA integrity number score) of RNA extracted from the head, body and trail regions from across all donors (n = 4) and preservation methods. One-way analysis of variance with Tukey’s post-hoc used to assess statistical significance. A: RNA integrity number across the pancreatic head, body and tail regions; B: RNA yield (ng/mg) across pancreatic head, body and tail regions.
