Self- and non-self-DNA on hands and sleeve cuffs.

ABSTRACT: Studying DNA transfer and persistence has become increasingly important over the last decade, due to the impressive sensitivity of modern DNA detection methods in forensic genetics. To improve our understanding of background DNA that could also potentially be transferred, we analyzed the DNA composition on the outside of sleeve cuffs and sampled DNA directly from the hands of four different collaborators upon their arrival at work during 25 working days. Sampling of their hands was repeated after several hours working in our department. The shedder status of the participants, as assumed from previous internal studies, was well re-produced in the study. However, we noticed that the DNA shedding capacity could also change drastically during the day, with one participant showing a more than s
