Summary
Vitreous humor can be a valuable source of DNA for forensic identification after death. The amount of DNA obtained depends on the sampling method and cause of death.
Area of Science:
- Forensic Science
- Molecular Biology
- Human Identification
Background:
- Postmortem identification is crucial in forensic investigations.
- Assessing alternative biological samples for DNA extraction is essential.
Purpose of the Study:
- To evaluate vitreous humor as a source of DNA for human postmortem identification.
- To determine the feasibility of using vitreous humor in forensic casework.
Main Methods:
- Vitreous humor samples were collected from 25 autopsies using two distinct methods.
- Standard organic extraction was employed for DNA isolation.
- DNA quantification was performed fluorometrically, and genetic profiles were generated using the AmpFlSTR SGM Plus kit and ABI 310 Genetic Analyzer.
Main Results:
- DNA yields varied significantly in vitreous humor samples.
- The cause of death influenced the quantity of DNA recovered.
- The sampling approach also affected DNA yield.
Conclusions:
- Vitreous humor is a viable source for forensic DNA analysis in postmortem identification.
- The effectiveness of vitreous humor as a DNA source is contingent upon the chosen sampling method.
