Stability of DNA Stored in Norgen’s Saliva DNA Preservative for 52 Months at Room Temperature
A preview of this application note (paraphrased from the introduction):
In recent years, attention has been turning to the use of non-invasive samples for genetic and diagnostic analysis, including the use of saliva. However, the isolation of high quality DNA from saliva is not without its problems. Adequate amounts of saliva must be extracted in an amount sufficient for testing. As enzymes that degrade DNA are found in saliva, methods must also be employed to protect the DNA in the sample. Norgen Biotek has developed a Saliva DNA Preservative which allows for the long-term preservation of saliva samples at ambient room temperature. In this application note, the long-term stability of saliva DNA in Norgen’s Saliva DNA Preservative is analyzed.
