Leukopaks are collected from healthy IRB consented donors, tested negative for HBV, HCV, and HIV, using the Spectra Optia® Apheresis System, where cell-rich mononuclear cells are extracted using a continuous flow system directly into a sterile collection bag containing the anticoagulant ACD-A. Up to 12 Leukopak collections can be performed on the same donor in a given year, providing an ample amount of PBMCs for large-scale experiments and research studies. Additionally, 200-300mL of plasma can be collected at the time of the donor draw.
The following are mean percentages of cell populations in a Leukopak:
• T cells – 55%
• Monocytes – 27%
• B cells – 9%
• NK cells – 8%
• CD34+ stem cells – 0.1%
• Granulocytes – 2.4%
We do not guarantee the percentage of cell populations in a Leukopak, as they can vary from donor to donor.
Cells were obtained using Institutional Review Board (IRB) approved consent forms and protocols.
