Summary
Stable GC-subtyping from blood stains on glass is possible for up to 64 days at room temperature. This method uses isoelectric focusing and enzyme-linked antibody detection for reliable forensic analysis.
Area of Science:
- Forensic Science
- Biochemistry
Context:
- Bloodstain analysis is crucial in forensic investigations.
- Preservation of biological evidence under various conditions impacts its analytical integrity.
Purpose:
- To evaluate the stability and reliability of GC-subtyping on blood stains stored at room temperature.
- To determine the maximum duration for successful GC-detection using specific laboratory techniques.
Summary:
- Blood stains on glass were subjected to GC-subtyping after storage at room temperature.
- Isoelectric focusing, semi-dry electroblotting, and enzyme-linked antibody detection enabled GC-detection.
- Successful detection was achieved even after 64 days of storage, indicating method robustness.
Impact:
- Establishes a viable timeframe for utilizing aged bloodstain evidence in forensic casework.
- Provides insights into the stability of GC-markers under specific storage conditions.
- Highlights potential methodical challenges and considerations for forensic laboratories.
