DNA from saliva: saliva is now an alternative to blood increasingly used as a starting sample to obtain genomic DNA. With our kits Oragenesi can collect, stabilize and store saliva at room temperature for months. The saliva sample can be used at any time as a source of genomic DNA on which to perform the most varied molecular analyses. Compared to blood, saliva is a completely non-invasive, painless, reliable and easy to use method.
