Product Description

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.
