Enhancing Detection of Trace Biological Evidence

Posted on by

Efficient collection and long-term preservation of trace samples are crucial for forensic investigations and genetic research. Trace samples, such as hair, saliva, or small blood stains, require careful handling to avoid contamination and degradation. Specialized collection kits, including swabs, tubes, and preservation agents, ensure sample integrity from the moment of collection through long-term storage. Techniques such as desiccation, low-temperature storage, and moisture control prevent DNA degradation, maintaining the viability of the sample for PCR, sequencing, and genotyping. This approach is essential for cold-case investigations, clinical diagnostics, and forensic analysis.

Key Features:

  • Efficient trace sample collection methods

  • Long-term preservation to prevent DNA degradation

  • Suitable for forensic and genetic analysis

  • Specialized kits for contamination-free storage

Application Scope:

  • Forensic crime scene investigations

  • Cold-case DNA recovery

  • Clinical and genetic research

  • Legal and criminal justice applications
