nonRNasefree

nonRNasefree refers to materials, surfaces, reagents, or environments that are not free of RNase enzymes. RNases are enzymes that degrade RNA, and their presence can compromise RNA integrity in molecular biology workflows. In contrast, RNase-free items are specifically treated or manufactured to minimize or eliminate RNase activity, reducing the risk of RNA degradation during experiments such as RNA extraction, RT-PCR, and RNA sequencing.

The term nonRNasefree is most often encountered in laboratory settings where RNA work is conducted. Sources of nonRNasefree conditions include untested or uncertified consumables, surfaces or instruments that have not undergone RNase decontamination, and reagents or water that have not been treated to remove RNases. Using nonRNasefree materials can lead to partial or complete degradation of RNA samples, resulting in poor data quality and unreliable results. Researchers may encounter nonRNasefree labeling in vendor documentation or as a cautionary note on product packaging.

To mitigate risks, laboratories typically rely on strict RNase-free handling practices. This includes using dedicated RNase-free consumables and tools, wearing gloves and changing them frequently, performing work in RNase-free workspaces, treating surfaces with RNase-decontaminating solutions, and using certified RNase-free water and reagents. Validation steps, such as assessing RNA integrity with electrophoresis or a bioanalyzer, help detect RNase contamination and guide corrective actions.

The term nonRNasefree is usually used descriptively to indicate absence of RNase-free status. It is generally preferred to describe items as RNase-free or not RNase-free, rather than as nonRNasefree, to communicate clearly about suitability for RNA-related applications.
