DNA sequences differ between species despite being composed of the same four nucleotides. The Oragene self-collection kit provides an easy, non-invasive way to collect high-quality DNA from saliva that is stable at room temperature for years, eliminating challenges of blood and buccal swab collection. The document does not provide information on the number of white blood cells in a cubic millimeter of blood.

1. Although DNA is composed of the same four nucleotides in all organisms, the sequence
of nucleotides is different for each species.
DNA in Saliva with Oragene
The Oragene self-collection kit for DNA from saliva from DNA Genotek, Inc. provides
an all-in-one system for the collection, stabilization, and transportation of DNA from
saliva. Blood samples are invasive to collect, as well as complex and costly to ship, store
and process. Buccal swabs provide a low quality and quantity of DNA.
Eliminate these challenges by collecting superior samples with the Oragene sample
collection product line.
• Easy collection, transportation and processing
• Painless, non-invasive collection of high-quality, high-quantity DNA
• DNA is stable for years at ambient temperature
• Proven on downstream applications
