Saliva is the most accessible and non-invasive source for extraction of human genomic DNA. The XpressDNA Saliva kit provides a simple, easy and efficient method to extract both host and bacterial DNA from saliva samples. The salivary DNA contains genomic DNA from buccal epithelial cells, WBCs and genomic DNA of the common microbiota of the individuals.
The DNA extracted by this method is amenable for all downstream applications such as PCR, Real Time-PCR, restriction digestion sequencing. It can also be used for metagenomic analysis of microbiome.
