Preserve High Quality RNA, including Viral RNA, for up to 2 Months
Norgen’s Saliva RNA Collection and Preservation Devices Dx are designed for safe and non-invasive saliva collection and preservation of RNA in saliva samples at ambient temperature. Each of the 50 Saliva RNA Collection and Preservation Devices Dx consists of 3 components: (1) Saliva Collection Funnel and Collection Tube, (2) Collection Tube Cap, and (3) Norgen’s Saliva RNA Preservative contained within a sealed squeezable ampoule. Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed and the contents of the Preservative Ampoule are then added and mixed with the collected saliva.
Saliva RNA Preservative
Norgen’s Saliva RNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of RNA from fresh saliva specimens. The buffer eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the buffer allow samples to be stored for up to 2 months at room temperature. The Saliva RNA Preservative also inactivates all bacteria, yeast and viruses present in the saliva sample.
Stability of RNA at room temperature for up to 2 months
Fig.1. Saliva samples were collected from numerous donors and mixed and then an equal volume of Norgen´s Saliva RNA Preservative was added.
Nucleic Acid and Isolation from Preservative
Saliva RNA can be isolated from the preserved saliva samples using Norgen’s Total RNA Purification Kit Dx. To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used.
