Biospecimen procurement, built for your protocol
From vaccine development to IVD to biopharma, your research defines the species, volumes, formats, and processing requirements for your biospecimens.
With our custom biospecimen services, we work directly to those requirements through on-site collection at our Arkansas facility, validated processing, and in-house QC under ISO 9001 controls to source exactly what your study calls for.

Agile sourcing with quality you can see
Our 40,000 square-foot Arkansas facility houses the largest USDA-inspected rabbit operation in the United States, plus 40 acres of company-operated farms and a curated network of trusted supply partners.
This level of visibility means that samples are traceable from animal to vial, and custom protocols can advance quickly from scoping to execution, without administrative friction.
Frequently Asked Questions
What is biospecimen procurement?
Biospecimen procurement is the sourcing, collection, and delivery of biological samples — blood, serum, plasma, tissues, and extracts — for research and diagnostic use. At Pel-Freez, procurement happens on-site at our USDA-inspected Arkansas facility, with uncompromising quality at every step from animal through QC-verified shipment.
Can I request single-lot or multi-lot sourcing?
Yes. Single-lot sourcing is available for studies that need long-term consistency, and multi-lot sourcing is available when broader donor variability is required.
Does every specimen ship with a Certificate of Analysis?
Yes. Every Pel-Freez biospecimen ships with a Certificate of Analysis or Certificate of Conformity documenting lot-specific test results against established specifications. Project-specific protocol, traceability, and QC documentation are available for custom biospecimen services on request.
