WebMessenger RNA (mRNA) provides researchers with insight into gene activity. Large-scale sequencing of mRNA enables researchers to profile what genes and genomic regions are active. In a typical workflow involving mRNA, total RNA is first analyzed for sample integrity before ribosomal RNA (rRNA) depletion, to ensure that the RNA is not degraded. WebSep 28, 2016 · An assessment of RNA integrity can be evaluated using the ratio of rRNAs 28s:18s. A higher ratio indicates better integrity. To test RNA quality, samples are tested on a 2100 Bioanalyzer (Agilent), which automatically measures the 28s:18s rRNA ratio and computes an RNA integrity number (RIN) .
