Collection of Genomic DNA by the Noninvasive Mouthwash Method for Use in Pharmacogenetic Studies

Abstract

The mouthwash method for collection of genomic DNA is a simple, inexpensive, and noninvasive method that poses less risk than venipuncture and may be used in a variety of settings. Genomic DNA in mouthwash is stable for prolonged periods at room temperature, and the quantity of DNA recovered from this method is more than sufficient for pharmacogenetic studies. Such an approach should be valuable to pharmacogenetic researchers and others who are conducting genetic research.
