Healthy PBMC

Healthy Donor PBMCs for Matched Controls and Assay Development

Healthy PBMCs are cryopreserved peripheral blood mononuclear cells (PBMCs) collected from IRB-consented donors with no reported chronic disease diagnosis. They are supplied as control and reference material: comparator arm for disease-state studies, baseline for assay development, and input for cell-based work that needs normal immune function rather than a disease phenotype.

Why Control PBMCs Are Distinct 

• Control quality bounds study quality. In a case-control immunology design, variance introduced by the control arm propagates into every downstream comparison. Controls sourced ad hoc, across different collection sites and processing windows, add batch effects that can be indistinguishable from a disease signal.
• Processing must match, not just donor status. These PBMCs are processed within 24 hours of collection and cryopreserved in CryoStor CS10; the same workflow used for our disease-state cohorts. That consistency is what makes them a valid comparator rather than simply a different sample.
• Normal immune function is the point. Healthy-donor PBMCs are used where an unperturbed baseline is required: establishing assay reference ranges, defining gating strategies before applying them to disease-state material, and serving as target or effector cells in cytotoxicity work.
• “Healthy” is an operational definition, not an absolute. Healthy donors are defined by absence of reported chronic disease, with medication history and infectious disease screening documented. Where a study needs a stricter definition, such as medication-free, non-smoking, or within a BMI band, that can be applied as a selection criterion rather than assumed.
• Single-donor volume enables longitudinal work. Large-lot configurations let a single donor supply every timepoint or plate in a study, removing donor-to-donor variability as a confounder.

Donor Selection Available

• Demographic matching to a disease cohort: age band, sex assigned at birth, and race/ethnicity 
• Medication status: medication-free donors where documented, or exclusion of specified drug classes
• Infectious disease screening: annual HIV, HBV and HCV screening status
• Age band: including younger and older adult cohorts for age-stratified designs; pediatric controls available separately as Healthy Pediatrics PBMC
• Lot size and configuration: cell counts from 10 million to 4 billion, including large single-donor lots for multi-timepoint studies
• Repeat draws from the same donor: where available, for intra-donor baseline work 
• Custom inclusion/exclusion criteria: prospective collection to a defined control profile

Frequently Asked Questions About Healthy PBMCs

Can you match healthy controls to my disease cohort?

Yes. Controls can be selected to match your case arm on age band, sex, and race/ethnicity. Share your cohort profile and we will scope availability or download our inventory to select the donors that match your needs. 

What does “healthy” mean for these donors?

Donors report no chronic disease diagnosis at the time of collection, with medication history and infectious disease screening documented. Stricter definitions such as medication-free, non-smoking, or a specified BMI range can be applied as selection criteria.

Can I get enough material from one donor for a whole study?

Yes. Large single-donor lots are available in cell counts up to 4 billion, which removes donor-to-donor variability across timepoints or plates.

Can I evaluate a lot before ordering in bulk?

Yes. LeukoLot™ pre-screening lets you qualify material against your assay before committing to a larger order.
