Why Choose CGT Global Leukopaks?
One of the Largest, Most Characterized Donor Pools
Access healthy, mobilized, and disease-state donors with deep demographic, phenotypic, and HLA data. Our comprehensive donor profiles enable you to target exactly the right starting material for your research — from age and ethnicity to rare disease indications — ensuring precision from the very first step.
Donor Recallability
When reproducibility matters, we make it possible to source from the same donor again and again. This reduces variability, strengthens your assay-to-assay consistency, and allows you to validate results with confidence.
Three FDA-Registered, CLIA-Certified Facilities
Our bi-coastal sites position us near major biotech hubs, providing fast access to research and clinical centers across the U.S. This geographic reach helps you meet even the tightest timelines.
Same-Day Collection & Shipping
We minimize transit time to preserve peak cell viability. Collections are processed and shipped the same day, meaning your samples arrive fresh and ready for immediate use — ideal for time-sensitive experiments.
Integrated Supply Chain
From donor recruitment to delivery, CGT Global manages every stage in-house. Without third-party intermediaries, we maintain quality control, shorten lead times, and eliminate supply chain uncertainty.
Dedicated Client Service Associate Support
You’ll have one consistent point of contact — a knowledgeable CSA who understands your research requirements, coordinates every detail, and keeps your project running smoothly from start to finish.

Types of Leukopaks
Fresh Leukopaks
Collected from healthy or disease-state donors and shipped immediately for use in time-sensitive applications. Best for short-term experiments requiring maximum cell viability.
Benefits
-
Receive cells immediately, eliminating the need for freezing
-
Maximize viability and functionality of delicate cell populations
-
Preserve specific subsets for specialized research or therapeutic applications
Considerations
-
Delays in shipment could impact cell viability
-
Tight collection-to-use timelines may require careful logistical planning
Cryopreserved Leukopaks
Frozen using validated protocols to preserve cells for long-term storage and flexible scheduling. Minimal viability loss upon thaw.
Benefits
-
Extend your experimental window by storing samples until needed
-
Improve batch consistency and reproducibility with standardized, preserved cell samples
-
Plan experiments with flexibility, without being constrained by collection schedules
Considerations
-
Freezing and thawing may result in some cell loss
-
Thawing and recovery time could slightly delay immediate use
Mobilized Leukopaks
Collected from donors treated with G-CSF to release more CD34+ stem cells into circulation. Ideal for cell therapy development and stem cell research.
Benefits
-
Acquire up to 10× more CD34+ stem cells compared with standard leukopaks
-
Achieve 2–4× higher total cell yields per donor
-
Enhance reproducibility with consistent cell supply from a single donor
Considerations
-
Mobilized leukopaks carry a higher cost than standard leukopaks, but the increase in yield and consistency often outweighs the investment.
GMP Leukopaks
CGT Global’s GMP-grade leukopaks are collected and processed under strict FDA and CLIA-compliant protocols, ensuring the highest standards of safety, sterility, and reproducibility. Ideal for clinical trials, translational research, and cell therapy applications.
Benefits
-
Meet regulatory standards for early- and late-phase clinical trials
-
Consistent, high-quality cell populations ready for therapeutic use
-
Validated processing with flow cytometry and quality control checks
-
Flexible options for fresh, mobilized, or custom collections
Considerations
-
GMP leukopaks may have a higher cost than research-grade products, but the assurance of regulatory compliance and clinical readiness justifies the investment.
