Are microRNAs stable enough to survive shipping from home to the lab?

Yes. MicroRNAs are remarkably stable biomolecules. They circulate in blood and urine protected within exosomes, microvesicles, and protein complexes that shield them from degradation by RNase enzymes. Yenos Analytical has specifically validated the stability of miRNA in urine samples during shipping. The OncuraKit collection process includes Yenos-validated preservation media that maintains miRNA integrity during overnight transit at ambient temperature. Yenos's 2025 publication (doi:10.3390/ijms26083822) confirms that specimens collected and shipped using the OncuraKit protocol produce reliable, quantifiable miRNA signals upon arrival at the CLIA-certified laboratory in El Dorado Hills, California.
