Abstract |
Specimens from sexual crimes are generally mixed stains consisted of sperm cells(from suspect) and virginal cells(from victim). We have combined two new methods - Differex(TM) system and FTA(R) technology- to overcome shortcomings of method that has been used before to separate sperm DNA from mixed stains. This methods have shown additional benefits and similar quality than using the only Differex(TM) system to the experiment. The result of our experiment represents the possibility that Differex(TM) system and FTA(R) technology would be useful methods for DNA analysis related to sexual crimes because this system can save time, labor and contamination for experiments. |
