Introduction
Mobilized leukopaks are essential starting material for advanced cell therapies, immune research, and manufacturing optimization. By mobilizing hematopoietic stem and progenitor cells (HSPCs) from the bone marrow into the bloodstream using agents like G-CSF or plerixafor, researchers can isolate higher yields of CD34+ and target immune cells for CAR T, NK, and other immunotherapy platforms. To understand how mobilization enhances yield and performance, see our detailed guide on Mobilized Leukopaks for Research.
As demand for high-yield, donor-characterized, and recallable leukopaks grows, researchers need suppliers who deliver consistently, fast, and with full traceability.
Below, we compare the top mobilized leukopak suppliers for 2026, based on transparency, donor mobilization programs, documentation, viability, and logistics.
Why Mobilized Leukopaks Matter
Mobilized leukopaks allow researchers to access:
- Higher CD34+ and progenitor cell yields per collection
- Consistent immune cell subsets for T, NK, and monocyte studies
- Improved viability and recovery rates during downstream isolation
- Better scalability for translational and preclinical programs
Mobilization also reduces the need for repeated donor collections, cutting costs and variability.
(See our guide on Buffy Coat vs. Leukapheresis to compare sourcing options.)
Top Mobilized Leukopak Suppliers for 2026
1. CGT Global
Best for: Rapid delivery, donor flexibility, and transparent documentation
CGT Global offers mobilized leukopaks from IRB-approved donors with options for G-CSF or plerixafor mobilization. Each collection includes detailed donor metadata, health screening results, and Certificates of Analysis with cell yield, viability, and mobilization protocol.
Key Highlights:
- Mobilization options: G-CSF, Plerixafor or both
- Fresh and cryopreserved formats available
- Donor-specific requests (CMV status, HLA, blood type, BMI) supported
- 24–48-hour fulfillment for in-stock material
- Real-time updates via live chat, email, or phone
Why Researchers Choose CGT Global:
Consistent yields, transparent donor data, and exceptional communication. Researchers appreciate the speed, responsiveness, and data clarity — no waiting weeks for basic donor info or QC results.

2. Charles River Laboratories
Best for: GMP-aligned donor collections and regulatory documentation
Charles River’s mobilized leukopaks are available under GMP-like conditions, targeting translational and IND-enabling research. They support both G-CSF and combination mobilization protocols, but lead times can be longer due to scheduling and documentation reviews.
3. STEMCELL Technologies
Best for: Frozen mobilized leukopaks and immediate inventory availability
STEMCELL sells frozen mobilized human peripheral blood leukopaks (Catalog #200-0130) with ≥9×10⁹ cells per bag.
List price: $7,835 USD for frozen inventory (ships within 1–2 business days).
They are premium-priced but appeal to labs needing quick access to large, mobilized lots with donor customization.
4. BioIVT
Best for: Custom mobilization and international fulfillment
BioIVT provides mobilized leukopaks using G-CSF and supports donor matching criteria. They’re a solid option for custom HLA-matched requests but require longer lead times and typically quote-only pricing.
5. iXCells Biotechnologies
Best for: Smaller mobilized batches and flexible collection windows
iXCells offers both fresh and cryopreserved mobilized leukopaks for preclinical studies. They focus on rapid collection for smaller research-scale orders and provide documentation upon request.
6. HemaCare (Now Part of Charles River)
Best for: Longstanding reliability and donor selection depth
HemaCare continues to provide mobilized leukopaks through Charles River’s infrastructure, supporting both G-CSF and plerixafor protocols. Their consistency and traceability have made them a go-to for large pharma clients.

FAQs
Can CD34 cells be isolated out and dispensed into different vial sizes?
Yes! CellsExpress now includes bulk CD34+ isolation from mobilized leukopaks, giving cell and gene therapy teams access to high yield, high viability CD34+ cells without the burden of in-house processing.
What’s the difference between G-CSF and plerixafor mobilization?
G-CSF increases circulating progenitor cells over several days, while plerixafor mobilizes more quickly and efficiently for certain donor profiles.
Are mobilized leukopaks available fresh and frozen?
Yes. CGT Global, AllCells, and others offer both formats. Fresh shipments typically arrive within 24–48 hours; frozen bags are ready-to-ship inventory.
How does mobilization affect downstream CD34+ yield?
Mobilization can increase CD34+ content by 5–10× compared to non-mobilized collections, improving stem and progenitor cell recovery.
Can I request specific donor attributes?
Yes. CGT Global supports donor matching based on HLA, CMV, sex, BMI, blood type, and other variables. Custom recruitment is available with rapid timelines.
