| Abstract: | Objective To establish a method of automatic extraction of sperms DNA from mixed stain. Methods 56 mixed stain samples were collected from casework. The samples were extracted by using DNA IOTM System and Biomel2000 Laboratory Automation Workstation, and then analyzed with 3130xl genetic analyzer. Results STR genetic typing was obtained from all 56 mixed stain samples. Conclusions DNA IQTM System and Biomek2000 Laboratory Automation Workstation can be used for sperms DNA extraction from mixed stain in forensic casework. |
