AllCells® GMP Fresh Leukopak
Discovery’s AllCells® GMP Fresh Leukopaks are collected by apheresis from peripheral blood of healthy donors. Our Leukopaks contain a high concentration of lymphocyte populations, T Cells, B Cells, NK Cells, and monocytes. AllCells maintains on-site, FDA-registered donor centers for the collection of all products from IRB-consented healthy donors providing customers with a streamlined process for procuring starting cellular materials for clinical and commercial manufacturing. A Certificate of Analysis (CoA) and summary of record (SoR) are provided with every order.
AllCells® GMP Leukapheresis Products are enriched in single-donor mononuclear cells (MNCs), allowing for scalability and reproducibility of manufacturing process. Our products are quality controlled for cell concentration and viability using a validated AO/PI protocol and pass a sterility test in accordance with USP <71> guidelines using compendial testing.

PROTOCOLS

AllCells® GMP Fresh Leukopak Difference
- Seamlessly transition from process development to manufacturing with RUO Fresh Leukopaks and GMP Fresh Leukopaks
- Process without delays with 99% deliverability rate of GMP products
- Maximize downstream manufacturing success by effectively screening, selecting, and retaining donors with desired attributes
Pre-Characterized Donor Selection Program
Discovery’s AllCells® Pre-Characterized Donor Selection Program is designed to expedite the donor selection process to accelerate the advancement of cell and gene therapies to the clinic and beyond. We obtain cryopreserved mononuclear cells (MNCs) from GMP eligible donors whose donor attributes, HLA (human leukocyte antigen) and KIR (killer cell immunoglobulin-like receptor) type have been annotated. Immunophenotyping is performed on the cryopreserved MNCs using our integrated analytical capabilities.
