Room-Temp DNA Blood Preservation

Posted on by

Long-term room temperature preservation of DNA blood samples relies on innovative scientific methods that prevent DNA degradation without the need for refrigeration. The key to successful room temperature storage lies in stabilizing the DNA and preventing the activity of nucleases, enzymes that can break down DNA.

Scientific Principles:

  1. Desiccation: Drying the blood on special absorbent materials, like FTA cards or other stabilizing agents, ensures that DNA remains intact by minimizing moisture, which is essential for preventing bacterial or enzymatic degradation.

  2. Chemical Stabilization: Some preservation methods involve the use of chemicals that protect DNA from oxidative damage and keep nucleases inactive, allowing for long-term storage at ambient temperatures.

  3. Inhibition of DNA Degradation: Specialized materials used in collection cards actively neutralize enzymes and other harmful agents, ensuring DNA remains stable and accessible for analysis over time.

Key Features:

  • Stabilization of DNA through chemical and physical methods

  • Avoids the need for cold storage, reducing logistical complications

  • Ensures DNA integrity over extended periods
