Abstract

Touch DNA, trace DNA or Low copy number has become an area of interest in recent years because of its importance when other type of biological evidences might not be available. However, minimal efforts have been devoted to develop the collection methods of touch DNA, and the success of DNA typing depends on the availability of existing DNA templates. In most cases DNA leaves sufficient quantity and quality of genomic DNA to produce a DNA profile. However, some variables affect the success of obtaining a good quality DNA profile. Such variables include shedder status, surface type, pressure of contact; other variables include the methods of DNA collection and the methods of DNA extraction.
触摸DNA的影响因素
近年来,由于在其他类型的生物证据可能无法获得的情况下具有重要意义,触摸DNA,痕量DNA或低拷贝数已成为一个感兴趣的领域。然而,很少有人致力于开发触摸DNA的收集方法,并且DNA分型的成功取决于现有DNA模板的可用性。在大多数情况下,DNA留下了足够数量和质量的基因组DNA来生成DNA图谱。然而,一些变量会影响获得高质量DNA图谱的成功。这些变量包括脱模状态、表面类型、接触压力;其他变量包括DNA采集方法和DNA提取方法。
