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. Saliva collection kits (Oragene) are designed to stabilize high molecular weight DNA by inhibiting degradation and preventing bacterial growth. Saliva is made up of water, electrolytes, mucus, and enzymes. states, The acquisition of high quality DNA for molecular assay from oral samples offers clear advantages in cost, handling, storing and shipping over acquisition of samples from blood. More recently, lab personnel in Australia performed a review of cases at the Division of Analytical Laboratories in New South Wales and found that in cases involving digital or penile sexual assault (without semen), Y-filer results were obtained on ~33% of vulval swab collected within12 hours of the assault5.

However, DNA samples collected from saliva where the donor spits into a collection device (Oragene) are quite different and offer higher yields and DNA quality than other oral DNA sample collection methods. A more comprehensive study4 in 2002 to determine if Y-STR DNA analysis could be beneficial in cases where there is no detection of spermatozoa found that of 104 sperm negative samples (collected anywhere from 2-192 hours after the alleged assault), 25 vaginal swabs, 3 anal swabs, and 2 oral swabs were positive for Y-DNA. Romantic right? Eating, Drinking, or Smoking before Swabbing. WebIn comparison, sperm cells are typically detected up to 3 days in vaginal swabs and up to 7 days in cervical swabs. 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.

For example, employers may use DNA tests to screen job applicants and only hire those with acceptable results. Y-STR analysis ignores the contribution of female DNA and focuses only on the male DNA present on the Y chromosome of the sample. Male saliva remains for three days. DNA has helped solve many cases when imaginative investigators collected evidence from nontraditional sources (see "Identifying DNA Evidence"). All rights reserved. This process occurs primarily with cells containing DNA; other cellular materials are eliminated through urine or feces. Further, just like fingerprints, DNA testing cannot tell officers when the suspect was at the crime scene or for how long. Further, a person's DNA is the same in every cell.
