The webinar will review existing scientific literature, describe lessons-learned and best practices for conducting experiments with touch DNA, and describe the initial results of a study designed to evaluate the stability of touch DNA under different environmental conditions. Five controlled environmental conditions were established with highly controlled temperature, relative humidity, and ultraviolet light levels. A formal randomization scheme was implemented to minimize sources of potential variability. The stability of both control DNA and touch DNA samples collected from donors was evaluated.
