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.
Highlights
Over the years, considerable technological development toward DNA typing in the bid to identify genetic markers has been undertaken
Raymond et al [6] conducted a study on the success rates of trace DNA identified that out of 252 trace casework samples from surfaces touched by hands, 44% did not produce a profile
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
