Molecular analysis of touched DNA samples collected from pistol surfaces

Abstract EN

Molecular analysis of touch DNA samples from pistol surfaces is important for crime scene investigation.

In this study touched samples were collected from different parts of pistol.

DNA extracted and quantified using different methods, then analyzed by mtDNA sequencing and STR profiling.

The results showed that pistol surfaces can be analyzed by mtDNA sequencing but not full STR profiled.

These results indicated the need for improving DNA extraction and STR profile kits for analysis low DNA amount
