Touch DNA


Touch DNA refers to DNA that can be obtained from skin cells left behind at crime scenes. The small amount of sample that is available must be collected carefully to maximize what is collected and extracted without introducing contamination. The small design of the CollectEject™ Touch DNA swab head helps to concentrate the sample and minimizes the amount of extraction buffer required for processing. This design increases the chances of generating a successful DNA profile with the fewest manipulations, reducing the potential of introducing contaminates.
