Features and Benefits
- Fast and easy processing using a rapid spin-column format
- Isolate high quality genomic DNA from fresh or preserved saliva samples
- Compatible with preserved saliva samples collected using Norgen’s Saliva DNA Collection and Preservation Devices (Cat. RU49000)
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 (Cat. RU49000), 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.
Background
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.

Supporting Data
Figure 1. High Quality and Yield of DNA from Saliva Samples. Total DNA was isolated from 250 µL of eight different fresh saliva samples using Norgen's Saliva DNA Isolation Kit (Lanes 1-8). For evaluation, 10 µL of each 100 µL DNA elution was run on a 1.2 % agarose gel. Note the high yield and quality of the DNA in all lanes. Lane M: Norgen's Fast runner 1kb DNA Ladder.
Figure 2. Real-time PCR Consistency from Saliva Samples. Norgen's Saliva DNA Isolation Kit was used to isolate DNA from 250 µL samples of fresh saliva. Ten 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. The 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 downstream applications.
Figure 3. Illumina MiSeq 16s rRNA metagenomics data from saliva samples preserved for over 6 years using Norgen's Saliva DNA Collection and Preservation Devices. The saliva DNA was isolated using Norgen's Saliva DNA Isolation Kit (Cat. RU45400) from saliva that had been preserved for various periods of time up to 6 years at room temperature. A) Principal Coordinate Analysis of 12 saliva microbiomes showing differences in the distribution of taxonomic classifications between samples up to kingdom level. B) Hierarchical clustering of 12 saliva microbiomes based on genus-level classifications, including a bar chart showing the relative abundance of genus-level classifications for each sample in the dendrogram.

FAQs
Spin Column
Column clogging may occur due to one or combination of the following factors:
- Centrifugation speed was too low or spin time was inadequate.
Check the centrifuge to ensure that it is capable of generating the required RPMs. Sufficient centrifugal force is required to move the liquid phase through the column. Also ensure that the correct spin times are followed. Spinning for a few additional minutes will help. - The sample is too large.
Too many cells were applied to the column. Ensure that no more than 0.5 mL of preserved saliva is applied to the column. Clogging can be alleviated by centrifuging for a longer period of time until the lysate passes through the column. - The lysate/binding solution mixture is not homogeneous.
To ensure a homogeneous solution, vortex for 10- 15 seconds before applying the lysate to the spin column.
Low genomic DNA yield may result from one or combination of the following factors:
- Incomplete lysis of cells Increased.
Proteinase K incubation time at 55°C may result in increased yields. -
The DNA elution is incomplete.
Perform an additional centrifugation of 2 minutes at 14,000 x g to ensure that all the DNA is eluted. -
DNA concentration in the saliva sample being used is low.
Some saliva samples contain very little DNA. This varies from individual to individual based on numerous variables. Increased proteinase K incubation time at 55°C may result in increased yields.
Poor downstream performance of DNA may result from one or combination of the following factors:
-
DNA was not washed with Wash Solution A.
Traces of salt from the binding step may remain in the sample if the column is not washed with Wash Solution A. Salt may interfere with downstream applications, and thus must be washed from the column. -
Ethanol carryover.
Ensure that the dry spin after the column wash steps is performed, in order to remove traces of ethanol prior to elution. Ethanol is known to interfere with many downstream applications.
RNA might get co-eluted with DNA in some cases. Carry out a digestion with RNase A on the elution if the RNA present will interfere with downstream applications. Refer to manufacturer’s instructions regarding amount of enzyme to use, optimal incubation time and temperature.
Swab samples can be processed using Saliva DNA isolation kit following a supplementary proptocol. However, please note that swab samples are best processed using Norgen's Microbiome DNA isolation kit.
