DNA is contained in blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc. Therefore, the amount of DNA in a sample could be overestimated and could result in reduced performance due to the under-loading of DNA into your assay. Both DNA yield and molecular weight will remain of high integrity for years at room temperature when collected in the Oragene stabilization chemistry. When extracting DNA from saliva, bacterial DNA is recovered along with the human DNA. After French kissing, most saliva is dissolved after a few hours. Saliva is the human bodys most accessible bio-fluid but, after many years, we continue to be surprised at how often we hear wrong perceptions about this robust and easy to access sample type.
