The RIN: an RNA integrity number for assigning integrity values to RNA

Weban rRNA ratio (28s/18s) of >1.5 is identified as shown (Fig. 2A). Such RNA samples are top grade or Grade 1 RNA samples. RNA samples are often partially degraded, demonstrating area under the curve below the 18s peak with RIN values between 5-7 and rRNA ratios <1.5. These are identified as Grade 2 (Fig. 2B). WebThe ratio of 28S and 18S rRNA peaks also is given.
