Saliva DNA purified using this kit is suitable for downstream applications such as PCR, Southern blotting, sequencing, and microarray analysis.
Available Formats
| Format | Catalog No. | Description |
|---|---|---|
| Spin Column | RU45400 | Simple spin column method for genomic DNA isolation |
| High Throughput | RU35200 | 96-well format for rapid, high-yield DNA isolation |
| Magnetic Bead System | RU55400, RU62900 | Magnetic bead-based DNA isolation, compatible with automated systems (IsoPure™, KingFisher, Hamilton Star/Vantage, Tecan) |
Background
Saliva is a non-invasive alternative to blood collection for genomic DNA extraction. DNA from buccal epithelial cells and leukocytes in saliva can be used for disease diagnosis, monitoring, and infection detection.
Norgen’s Saliva DNA Isolation Kit enables fast and reliable DNA isolation from both preserved 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 fresh saliva samples using Norgen’s kit.
For evaluation, 10 µL of each 100 µL elution was run on a 1.2% agarose gel.
High yield and quality were observed in all lanes.

Figure 2. Real-time PCR Consistency from Saliva Samples
DNA was isolated from 250 µL of fresh saliva (10 samples from one donor).
5 µL of each elution was used in real-time PCR for GAPDH amplification.
Consistent Ct values confirmed reproducibility and high DNA quality.

FAQs (Selected)
Q. What to do if column gets clogged?
Ensure proper centrifugation speed/time, apply ≤0.5 mL saliva, and vortex lysate before loading.
Q. Why low DNA yield?
May result from incomplete lysis or low DNA concentration in sample; extend Proteinase K incubation.
Q. Poor downstream performance?
Ensure thorough washing and removal of ethanol before elution.
Q. RNA contamination?
Perform RNase A digestion if RNA interferes with downstream use.
Q. Can process swab or non-human saliva?
Yes, with supplementary protocol; validated on canine samples.
