A leukopak is an enriched leukapheresis product collected from normal peripheral blood. It is composed of a variety of blood cells including monocytes, lymphocytes, platelets, plasma, and red cells. A leukopak contains a higher concentration of cells as compared to standard venipuncture collection methods or buffy coat products.
Leukopaks are collected in HemaCare’s FDA-registered collection centers from IRB consented healthy human donors by leukapheresis using the Spectra Optia® Apheresis System CMNC collection protocol in ACD-A anticoagulant. Cryopreserved leukopaks are cryopreserved on site immediately following collection.

Use fresh leukopaks immediately upon receipt.
For cryopreserved leukopaks, either prepare cells for long-term storage in Liquid Nitrogen vapor phase or thaw for use. Storage in liquid phase nitrogen is NOT recommended. Short-term storage of cells (less than 2 weeks) at -80°C is acceptable but should be minimized to ensure maximum stability. Once thawed, samples must be used immediately.
Testing: Donors are tested for HBV, HCV, HIV, HTLV, WNV, Trypanosoma cruzi, and Syphilis.
