A masked rapist was convicted of forced oral copulation when his victim's DNA matched DNA swabbed from the suspect's penis 6 hours after the offense. Until this technique is readily available, it is important to recall that DNA analysts already have a validated method to select only male DNA containing cells with the use of Y-STR typing. 4.

The general detection window in oral fluids is 5 to 48 hours, but again, that window can be longer for people who use a substance often or for a long period of time. Phenolics can be of concern; however, these are not within Oragene and prepITL2P reagents, so this is not an issue for Oragene/saliva samples. In addition, a poster recently presented by the Broad Institute stated: To date, we have sequenced over 1585 (Oragene) saliva samples to 30x coverage using the HiSeqX (Illumina) Given this experience, we are confident sequencing patient samples from (Oragene) saliva can be cost effective and produce high quality results for research and clinical studies.[7]. Generally speaking, however, DNA can be recovered from dried saliva for up to several years.
