Relative detection levels of spiked-in cel-miR-39 in four biofluids. Levels of cel-miR-39, spiked during workup, were determined in serum (A), urine (B), perfusate (C), and bile (D) from six patients and their donor organs. Results are shown of four different methods and presented as scatter plots (mean ± SEM). RN; Qiagen miRNeasy kit, QP; Qiazol in combination with the dr. GenTLE precipitation carrier, NG; NORGEN Total RNA isolation kit, and CU; miRCURY RNA isolation kit - biofluids. The mean of the levels with the RN isolation method per liquid were set at 100% . Data are presented as mean ± SEM. *: p < 0.05, **: p < 0.01, Mann-Whitney U test
