Saliva DNA Collection and Preservation Devices (50)

Norgen's Saliva DNA Collection and Preservation Devices are designed for 1) simple and non-invasive saliva collection and 2) preservation of DNA in saliva samples at ambient temperature. Each of the 50 Saliva DNA Collection and Preservation Devices consists of 3 components: (1) Saliva Collection Funnel and Collection Tube, (2) Collection Tube Cap, and (3) Norgen's Saliva DNA 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. The Saliva Collection Tube is subsequently sent to the laboratory for DNA isolation and analysis. DNA can be isolated from the preserved saliva samples using Norgen's Saliva DNA Isolation Kit (Cat# RU45400). Each of Norgen's Collection Tubes is labeled with a unique serial number that can be used for secure and anonymous tracking of the sample. The saliva DNA in preserved samples is stable for more than 5 years at room temperature. This kit is ideal for collecting and preserving DNA samples for epidemiological and population studies.

Saliva DNA Preservative

Norgen's Saliva DNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. The buffer prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, 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 more than 5 years without any detectable DNA degradation.

Nucleic Acid Isolation from Preservative

Saliva DNA can be isolated from the preserved saliva samples using Norgen’s spin-column based Saliva DNA Isolation Kit (Cat# RU45400). Also, these devices can be purchased with reagents to allow for optimized isolation of the preserved DNA using an alcohol precipitation method (Norgen’s Saliva DNA Collection, Preservation and Isolation Kit, Cat# RU35700).

Shelf Life and Handling

  • When stored at room temperature, unused Norgen Saliva Preservative Tubes are stable through to the collect-before date without any reduction in performance. Please see the device insert or tube label for collect-before date.
  • Once collected, saliva is stable for more than 52 months when kept tightly sealed and stored at room temperature.
  • The Collection Tube, the Collection Funnel and the Device Container of each Individual Saliva DNA Collection and Preservation Device are recyclable.
