Saliva DNA Isolation Kit RU45400 50 Preps

Saliva DNA Isolation Kit

This kit provides a fast and simple spin column procedure for isolating genomic DNA from saliva samples collected and preserved using Norgen’s Saliva DNA Collection and Preservation Devices, as well as fresh saliva samples.

Saliva DNA purified using Norgen’s kit is of the highest quality, and is compatible with a number of downstream research applications including PCR, Southern Blot analysis, sequencing and microarray analysis.


Saliva represents an excellent non-invasive alternative to blood collection.  Human genomic DNA extracted from buccal epithelial cells and white blood cells found in saliva can be used in various applications in diagnostics. Saliva DNA can be used for the detection of biomarkers to diagnose a disease, follow the diseases progress or monitor the effects of a particular treatment. Saliva DNA can also be used to diagnose particular types of infections. Isolation of DNA from saliva has become an attractive alternative to isolation from blood or tissue due to the fact that sample collection is non-invasive, the samples can be collected by individuals with little training, and no special equipment is required. Norgen’s Saliva DNA Isolation Kit provides a fast and simple procedure for isolating genomic DNA from both preserved saliva samples and fresh saliva samples.
