Am J Clin Pathol. The DNA in saliva originates from cells that are shed from the inner linings of the mouth and from white blood cells. Overall, saliva is less expensive than blood for DNA collection when factoring in all costs associated with the sample collection procedure. For Sci Intl. Don't know bout 6 months but if your exchanging bodily fluids you're carrying each others trace of DNA I believe. No semen was identified on the victim's vaginal swab or underwear, but Y-STR analysis was used to identify male DNA that matched the suspect in the victim's underwear. The human body is covered in bacteria, most of which we are not aware of because they live inside our bodies where we cannot see them. Both DNA yield and molecular weight will remain of high integrity for years at room temperature when collected in the Oragene stabilization chemistry. There are no suggestions because the search field is empty. Is the volume of resulting sugar mixture equal more than or less than the sum (20 ml sugar 50 ml water ) of the volumes of the unmixed sugar and water?

Blood collection is often considered the golden standard for DNA quality and it is an established practice across hospitals, clinics, and labs worldwide. In fact, studies have shown that changes in the bacterial composition of the mouth can lead to conditions like periodontitis (gum disease) and tooth decay. So every 1,000 years, 75 per cent of the genetic information is lost. When compared to other oral sampling methods, such as buccal swabs or mouthwash, a 2mL saliva sample collected with Oragene yields approximately 11% bacterial DNA, substantially lower than mouthwash at 66% and cytobrushes at over 88% bacterial DNA[2]. Saliva samples are a viable alternative to blood samples as a source of DNA for high throughput genotyping.
