RNA integrity number

The RNA Integrity Number (RIN) is a metric used to assess the quality and integrity of RNA samples, particularly in molecular biology and genomics. It provides a quantitative measure of RNA degradation, which is crucial for ensuring reliable results in downstream applications such as quantitative PCR (qPCR), microarray analysis, and RNA sequencing. The RIN ranges from 1 to 10, where: - **10** indicates intact RNA with no degradation, - **1** indicates highly degraded RNA.
