From: Examining smoking-induced differential gene expression changes in buccal mucosa
Buccal mucosa total RNA from smokers and nonsmokers, the group b buccal samples. Sample 1, total RNA from whole blood is added for comparison. Compare to Figure 2. For example Sm26a and Sm26b are from opposite cheeks of same subject and show some similarity in migration pattern. The same variation in peak heights and species between samples is seen here as in Figure 2. RIN, RNA integrity Number; NA, no RIN determination possible.
