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. 49000), as well as fresh saliva samples.
Saliva DNA purified using Norgen’s Saliva DNA Isolation Kit Dx kit is of the highest quality, and can be used with any downstream in vitro diagnostic application employing enzymatic amplification or other enzymatic modifications of DNA followed by signal detection or amplification.
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.

iDi® stands for High Discrimination of mismatches at the 3’-terminus of primers in PCR. This myPOLS Biotec enzyme family is optimized for this feature and is the first choice for applications that rely on this property such as allele-specific PCR (asPCR) or allele-specific amplification (ASA).HiDi® Taq 2x PCR Master Mix – ready to use mix simplifies your PCR setup. Only target-specific primers and template need to be added as the mix contains all components for a successful and reliable PCR. This ensures reproducible results, significantly reduces set-up times and the risk of pipetting errors.Please note: This PCR mix is also available as a mix with a nuclease deficient variant, featuring higher robustness towards potential PCR inhibitors and compatibility with real-time dyes such as our GreenDye.Benchmarking with products of competitors conducted by us and others show that the HiDi® DNA polymerase family is the first choice for highly selective PCRs, such as genotyping by allele-specific PCR, HLA genotyping, analysis of single CpG methylation sites or the detection of mutations in a high background of wild-type sequences. By using HiDi® Taq DNA polymerase, less than 10 copies of a mutation can be detected in a background of >10.000 wild-type copies straight away without any other tedious assay optimization.HiDi® Taq DNA polymerase harbours a nuclease function and therefor is also suitable for use with hydrolysis probes (TaqMan® probes etc.). It has also been shown that HiDi® DNA polymerase family is highly suitable for quality control and mutation identification in CRISPR-Cas or TALEN-based applications.Several independently conducted studies show that HiDi® Taq DNA polymerase is ideally suited for use in asPCR in numerous research areas ranging from mutation detection to genome editing.

Example Primer Design
Matching vs. mismatching nucleotide is placed at the 3′-end of the primer for best discrimination results.
Example Results – There´s no accounting for taste
Cilantro: some people love it in their food, some hate it. Here we are detecting a genomic SNP (rs72921001) in HeLa genomic DNA. This SNP is reported to be close to a number of genes coding for olfactory receptors. (Reference: Eriksson N. et al. (2012), “A genetic variant near olfactory receptor genes influences cilantro preference.”)
Considering, that only the C-allele specific primer is extended and yielding in a specific amplicon, we can conclude a genetic predisposition in disliking cilantro, as this SNP is significantly associated with detecting a soapy taste to cilantro.
Allele-specific PCRs were performed from 1 ng/µl of HeLa gDNA in the presence of a realtime dye, indicating the amplification of the C-allele specific primer only. The A-allele specific primer is discriminated, thus not amplified up to 50 cycles.
PCR products were subsequently analysed on a 2.5% agarose gel. Specific product is visualized by ethidium bromide staining at the amplicon length of 109 bp.
