Norgen’s Saliva DNA Isolation Kit provides a fast and simple 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. 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. 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.
Purification is based on spin column chromatography. Saliva DNA can be isolated from either saliva samples collected and preserved using Norgen's Saliva DNA Collection and Preservation Devices, or fresh saliva samples. Preserved saliva samples, or fresh saliva samples mixed with the provided Lysis Solution are first incubated for 1 hour. Next, Proteinase K and Binding Solution are then added to the sample, followed by the addition of ethanol. The resulting solution is loaded onto a spin-column (BIND). Under these conditions only the genomic DNA will bind to the column while most of the contaminating RNA and cellular proteinaceous components are removed in the flowthrough. The bound DNA is then washed to remove any remaining impurities (WASH). Lastly, the purified genomic DNA is eluted into 200 µL of the provided Elution Buffer (ELUTE). Please see the procedure flowchart to the right.
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. FEATURES AND BENEFITS
- Fast and easy processing - Rapid spin-column format allows for the processing of 10 samples in 30 minutes.

Figure 1. High Quality and Yield of DNA from Saliva Samples. Total DNA was isolated from 250 µL of eight different saliva samples using Norgen’s Saliva DNA Isolation Kit (Lanes 1-8). For evaluation, 20 µL of each 100 µL DNA elution was run on a 1.0% agarose gel. Note the high yield and quality of the DNA in all lanes. Lane M: Norgen’s HighRanger 1kb DNA Ladder. |
Figure 2. Detection of 5S rDNA from Saliva Samples. Norgen's Saliva DNA Isolation Kit was used to isolate DNA from 250 µL samples of saliva mixed with equal amounts of Lysis Solution. From the 100 µL elution, 1 µL, 3 µL, 6 µL and 9 µL of saliva DNA was directly mixed to real-time PCR master mix (total reaction volume 20 µL), and the real-time PCR reaction was performed. 5S rDNA was successfully amplified from the different template volumes without any inhibition, indicating the excellent quality of saliva DNA for down stream applications. |
Figure 3. Real-time PCR Consistency from Saliva Samples. Norgen's Saliva DNA Isolation Kit was used to isolate DNA from 250 µL samples of saliva mixed with equal amounts of Lysis Solution. Eight samples were used from same donor. From the 100 µL elution, 5 µL of saliva DNA was directly mixed to real-time PCR master mix (total reaction volume 20 µL), and the real-time PCR reaction was performed. GAPDH gene was successfully amplified from the different samples without any inhibition and at the same Ct, indicating the isolation consistency and the excellent quality of saliva DNA for down stream applications.
