Leukopaks are enriched leukapheresis products collected from healthy and consenting donors using the Spectra Optia® Apheresis System following an IRB-approved protocol. Leukopaks typically contain up to 50% T cells, 20% monocytes, 10% B cells, 10% NK cells, 3% granulocytes, and 3% hematocrit.
Leukapheresis results in high yields of single-donor mononuclear cells (MNCs) compared to venipuncture collection or buffy coat isolation. Leukopaks allow for scalability and reproducibility of experiments by limiting the impact of donor-to-donor variability. AllCells offers Leukopaks and isolated cell populations from leukapheresis material for a variety of applications.
AllCells can manufacture the following leukopak products:
Whole – Blood bag collected from leukapheresis (Leukopak)

Leukopaks are collected by apheresis, a procedure in which collection and enrichment of white blood cells from multiple volumes of healthy donor peripheral blood are achieved by a simultaneous return of non-targeted blood cells to circulation. This procedure results in large yields of single-donor mononuclear cells (MNCs), allowing for scalability and reproducibility of experiments, limiting the impact of donor-to-donor variability. AllCells offers Leukopak products in fresh, cryopreserved, or frozen, and in different formats*: Whole Apheresis Tissue, Mononuclear Cells (PBMCs), Subpopulations: T Cells, B Cells, NK Cells, and Monocytes, Cultured Cells: Macrophages and Dendritic Cells.
*Cell type, cell selection method, and unit size (by volume or cell count) vary depending on format.
