Around this same time period, the forensic DNA community gained a new tool in its arsenal - that of Y-STR typing. Phlebotomists, medical supplies and shipping requirements (dry ice, containers, and overnight delivery) add an estimated $40 per sample, not including freezer storage[8]. 5. This was revealed by a study that was conducted at Comenius University in Slovakia. Certain genetic variants are included in the DNA that is present in saliva. Time is also a factor in how much DNA will remain in your mouth. According to the study, the saliva was detected by finding a Y chromosome, which means that this method can only be used to identify male DNA in female saliva after a kiss is exchanged. These variant can vary in how long they take to break down and be flushed out of the mouth. Paternity refers to fatherhood. Where can DNA evidence be found at a crime scene? Non sperm male cells could be epithelial or inflammatory cells that are indistinguishable from the victim's cells with conventional cytology." The median yield ofDNA from a 2 ml saliva sample using Oragene is 110 g[4] when purified according to the optimized Oragene protocol using prepITL2P and measured by the highly specific Fluorescence/DNase method. Sensitivity-focused assays based on the SRY (single-copy gene) and DYS (multi-copy gene) sequence motifs confirmed the presence of male DNA in female saliva after 10 and even 60min after kissing, respectively.

The latest findings published in the journal Forensic Science International: Genetics, show that the man's DNA was still present in the women's saliva and could be identified through amplification after at least an hour. The length of time that DNA can be recovered from dried saliva depends on a number of factors, including the amount of saliva present, the conditions under which it dried, and whether it was exposed to UV light or other environmental stresses. This answer is: After French kissing, most saliva is dissolved after a few hours. The researchers found that male epithelial cells were able to be identified even in samples where no ejaculation had taken place, thus proving that male DNA can be transferred to the vaginal canal through intercourse without ejaculation. 19:319326 (2007).
