Storage and Distribution

After processing and QC, samples are stored using state-of-the-art ultra-low-temperature freezers and liquid nitrogen cryo tanks, supported by full environmental monitoring, redundant power systems, and 24/7 alerts. Proper storage is critical to preserving the integrity, stability, and scientific utility of biospecimens, ensuring they remain suitable for high-impact clinical research, biomarker discovery, and regulatory submission.

Coriell uses specimen-specific storage protocols, including:

  • –20°C for short-term storage of certain reagents and DNA preparations
  • –80°C for long-term storage of RNA, serum, plasma, and isolated nucleic acids
  • –196°C in vapor-phase liquid nitrogen tanks for cryopreserved cells and live biological material

Coriell recently expanded its infrastructure with new vapor-phase nitrogen storage tanks, which reduce contamination risk and provide stable long-term cryogenic conditions. 

Controlled distribution involves:

  • Validated thawing protocols and solvent removal procedures
  • Chain-of-custody documentation and audit trails
  • Full compliance with ethical, biosafety, and shipping regulations, including IATA standards

Coriell distributes thousands of biospecimens annually to researchers in over 50 countries, supporting a global network of scientists and institutions. A dedicated biobanking logistics team manages all aspects of specimen shipment, ensuring accuracy, speed, and compliance. In parallel, our customer service team provides personalized support, addressing inquiries, coordinating orders, and maintaining strong client relationships throughout the research lifecycle.
