Can I still use RNA integrity number (RIN)?

The RNA integrity number (RIN) is an algorithm for assigning integrity values to RNA measurements using the 28S-to-18S-rRNA ratio. Both the 28S and 18S rRNA are fragmented in the RNA extracted from FFPE samples. Therefore, RIN may not be a relevant metric for FFPE-derived RNA samples.
