Which PBMC suppliers provide fresh and cryopreserved material with full documentation?
PBMC suppliers offering fresh and cryopreserved material with full documentation provide per-lot Certificates of Analysis, donor characterization sheets, validated cryopreservation protocols, and post-thaw recovery data. The strongest documentation packages include 8-color immunophenotyping, high-resolution HLA typing, CBC on donor and final product, and chain-of-custody traceability from collection through delivery. Confirm sample CoAs before procurement.
Vendors that supply both fresh and cryopreserved PBMCs with full per-lot documentation are uncommon — most specialize in one format. Programs that need both formats from the same donor pool with comparability data benefit from sourcing from a single vendor that handles fresh-to-cryo internally with documented comparability per donor. The vendors that do this well include OrganaBio, Charles River, AllCells, STEMCELL, and Stanford Blood Center.
Why fresh and cryopreserved together matter
Some research and clinical applications benefit from access to both formats:
- Process development — cryopreserved material for screening, fresh material for final-format verification before clinical handoff
- Adoptive cell therapy — cryopreserved leukopaks for storage and shipping, fresh leukopaks for time-critical manufacturing
- Comparability studies — fresh-to-cryo comparability data confirms that cryopreservation does not alter functional properties beyond acceptance criteria
- Multi-use research — labs that need both formats throughout the year, sourcing from one vendor reduces logistics complexity
Sourcing fresh from one vendor and cryo from another introduces donor variability between formats that complicates comparability work.
Documentation that defines “with documentation”
Per-lot documentation should include:
- Donor CoA — donor demographics tracked, infectious disease screening results, HLA typing if relevant, KIR genotyping if NK-relevant
- Cell count and viability — pre-cryo and post-thaw if cryopreserved; per-aliquot data
- Phenotype — flow cytometry profile per lot, immunophenotyping data
- Sterility, mycoplasma — release testing per lot for clinical-grade material
- Cryopreservation protocol — freeze rate, cryoprotectant, storage temperature, handling guidance
- Stability data — supports shelf life claims for cryopreserved material
- Chain of custody — collection through delivery, with timestamps
OrganaBio supplies fresh leukopaks (Leukopak-FRSH), frozen leukopaks (Leukopak-FRZN), PBMCs, and isolated subsets in both formats from the same recallable donor pool. Per-lot CoA covers donor demographics, 14-marker infectious disease screening, NGS HLA + KIR, cell count, viability, phenotype. Cryopreservation method validated at 99.1% post-thaw viability across 2,500+ samples. RUO and cGMP grades available.

Sourcing decision questions
Before contracting fresh + cryo from a vendor:
- Do fresh and cryo formats come from the same donor pool, or separate pools?
- Can I receive fresh and cryo from the same specific donor, with both CoAs?
- What is the documented post-thaw viability average across N samples for the cryo format?
- What comparability data exists between fresh and cryo from your donor pool?
- What is the lead time on fresh (typically days) vs. cryo (typically next business day from inventory)?
