Usage Methods and Extraction Techniques for Shed Cell Collectors

Posted on by

Shed cell collectors are specialized tools used for collecting biological samples, primarily focusing on shedding cells from surfaces or tissues in forensic and medical applications. The collection and extraction techniques ensure the preservation of cellular material for accurate analysis.

Usage Methods:

  1. Preparation: Before use, ensure the collector is sterile and ready for sample collection. Ensure all equipment, such as gloves and tools, is also sanitized.

  2. Sample Collection: Place the collector onto the surface or tissue from which cells are to be collected. Gently rub or press the collector to capture the cells while avoiding contamination.

  3. Sealing: After collection, seal the collector properly to prevent contamination or loss of material during transport to the lab.

  4. Labeling: Properly label each sample with essential information, such as the case number, collection site, and time of collection.

Extraction Techniques:

  1. Cell Lysis: Use chemical agents or mechanical methods to break open the cells and release the DNA or other biological material for analysis.

  2. Centrifugation: After lysis, centrifuge the sample to separate the cellular material from the surrounding medium.

  3. DNA Extraction: Apply standard DNA extraction kits or methods (e.g., silica-based, magnetic bead-based) to isolate DNA from the collected material.

  4. Preservation: Ensure proper storage conditions, such as freezing or dry storage, to maintain the sample integrity until analysis.

Key Features:

  • Ease of Use: Shed cell collectors are designed for simplicity and efficiency in various environments, particularly forensic and medical fields.

  • Accurate Collection: They are highly effective at collecting a wide range of cell types without contamination.

  • Reliable Extraction: The use of standard extraction techniques ensures high-quality DNA and biological material for testing.

  • Versatility: Suitable for use in multiple environments, including crime scenes, medical clinics, and research labs.

Scope:
Shed cell collectors are used in forensic investigations, medical diagnostics, and genetic research, ensuring efficient and uncontaminated sample collection for reliable results.

Rigid-Base Shed Cell Collectors for Forensics

Posted on by

Hard-base shed cell collectors are specialized tools used in forensic field work for the collection of biological samples, particularly blood and other bodily fluids. These collectors are designed to ensure the effective capture of cells and preserve sample integrity for subsequent analysis in forensic investigations.

Application in Forensic Field Work:

  1. Blood Collection: Hard-base shed cell collectors are ideal for collecting blood samples from crime scenes, accident sites, or suspected areas of interest. The sturdy, hard-base structure helps stabilize the collection medium, preventing contamination.

  2. Biological Evidence Preservation: The collectors preserve the DNA or cellular material by minimizing exposure to environmental factors like temperature and moisture, which can degrade the sample.

  3. Ease of Use: These tools are designed for easy and efficient collection in challenging field environments, providing forensic investigators with reliable, contamination-free samples for analysis.

  4. Chain of Custody: Hard-base collectors can be securely sealed and labeled, ensuring that the sample’s integrity is maintained from collection to laboratory analysis.

Key Features:

  • Durability: The hard-base design allows for safe and secure sample collection, even in rugged field conditions.

  • Reliable Preservation: Ensures the integrity of DNA and other biological markers during transportation and storage.

  • Contamination Prevention: The design minimizes contamination, ensuring the accuracy of forensic analysis.

  • Ease of Transport: Compact, secure packaging allows for easy transport of samples to forensic labs.

Scope:
These collectors are widely used in forensic investigations, crime scene analysis, and legal
