According to The Hastings Center, more than 300 million biospecimens are stored in the United States in public and private biobanks. As the number rises, sample utilization is increasingly coming into question.Frozen aliquotting eliminates the degradation of biomolecules associated with repeated freeze-thaw cycles and preserves sample quality. Sample managers can perform QC/QA testing on stored samples without thawing, improving the quality of data obtained from them.
The ability to produce frozen aliquots enables biobanks to distribute smaller sample volumes and preserve valuable biospecimens. Rare disease, late-stage disease, pediatric and other rare samples can now be utilized by a larger number of researchers for a wider range of studies without compromising samples. Researchers can purchase smaller sample quantities, making the utilization of stored sample collections more affordable.
