Figure 1. Quality results of RNA isolated from mouse eyelids. A: High-quality 18S and 28S RNA was isolated from 2-year-old male and female C57BL/6 mice according to the Bioanalyzer plots of the 2-year-old male (B) and female (C) mouse eyelid meibomian glands. The average quality of sequence information was 32.6, and the Ribosome Integrity Number (RIN) values exceeded 9 on a scale of 1–10.
