Why Choose CGT Global’s GMP Leukopaks?
Pre-Clinical (RUO) vs. Clinical (GMP) Products
At CGT Global, we understand that every project is different. That’s why we work closely with each client to determine the specific compliance requirements based on how our materials will be used.
With over a decade of experience as a trusted provider of RUO and GMP-compliant healthy donor materials, we offer flexible, customizable solutions to support researchers and drug developers at every stage of their work.
Partner with CGT Global, where expertise meets flexibility.



Dependable Donors for Reproducible Science
At CGT Global, we recognize that allogeneic therapies, such as CAR-T, demand the right donor, qualified through rigorous screening and compliant with 21 CFR 1271 Subpart C. These donors must meet strict eligibility requirements and undergo extensive testing before contributing raw material for clinical manufacturing.
To address this critical need, we offer a unique, program-specific donor solution managed by our specialized donor recruitment and collection team. Whether you’re launching a new program or scaling an existing one, our team works closely with you to build a tailored strategy that supports every stage, from donor recruitment through to product fulfillment.

Tour Our GMP Cell Processing Facility
Step inside CGT Global’s advanced GMP laboratory, where precision meets compliance. Our facility is purpose-built to support clinical-grade manufacturing, providing a controlled environment for the processing, expansion, and cryopreservation of critical cell populations.
Cryogenic Storage & Preservation
CGT Global GMP Laboratory houses LN2 cryogenic storage systems, including vapor-phase cryo tanks equipped with automated temperature monitoring and backup power redundancy to maintain sample integrity at all times. All cryopreserved materials undergo validated controlled rate freezing protocols and are tracked through our validated inventory system.
Closed-System Cell Processing with CliniMACS Prodigy®
We utilize automated, closed-system cell isolation and enrichment, minimizing contamination risk and supporting GMP-grade reproducibility. For phenotypic analysis of expanded cell populations, we employ flow cytometry. Together, these technologies support applications such as CD34+ enrichment, T-cell subset selection, and detailed immunophenotyping.
Integrated QC & Traceability
Samples move through a fully integrated workflow that includes:
- Real-time viability and phenotyping via flow cytometry
- Mycoplasma and endotoxin testing for Cryopreserved GMP Leuakopaks
- Digital chain-of-custody tracking
We welcome collaborators and clients to tour the facility virtually or in person, and witness firsthand the rigor and reliability that define CGT Global’s clinical operations.
