Our findings showed that NaCl 0.9% swabbing solution prior to Lysis extraction provided the optimum method of DNA recovery from both glass and metallic slides, in comparison to SDS 2% wetting solution and QIAmp® DNA Investigator® Kit. The features of that assay make it ideal for personal identification in crime scene investigations at military organizations. Furthermore, it has been shown that these methodologies are applicable for large-scale analysis.
