Figure 1

Comparison of the yield and purity of extracted DNA between protocols. (A) DNA yield and (B) DNA quality (n = 7 samples/protocol). DNA yield is expressed as DNA concentration (ng/μl) normalized by quantity of lung tissue used for DNA extraction. Solid black lines indicate the median, and the lower and upper bounds of the box represent the 25 and 75% quartiles. Outliers, defined as falling outside the 10% and 90% quartiles, are indicated with black circles. Significant differences specified in the figure are based on ANOVA or the Kruskal–Wallis tests.
