Figure 2

RNA quantity and quality in different sample types. Details on RNA quantity are shown in (a,b) including the standard deviation (SD). Data on RNA integrity number (RIN) are present in (c,d) including the SD. The normal distribution (ND) was calculated by the Shapiro-Wilk test. The boxes (a,c) enclose samples within the 25th to the 75th percentiles. The lowest and largest values are visualised using bars. The horizontal line represents the median.
