Start experiments when you want to with large numbers of leukocytes, including peripheral blood mononuclear cells (PBMCs). As a cryopreserved product, frozen leukopaks provide samples from specific donors that can be processed when the end-user is ready. We help you get the cells you need with personalized service, custom products, flexible delivery times, and multiple size options.

Each frozen leukopak is a highly concentrated, low-volume apheresis collection from a single, normal donor, using Institutional Review Board (IRB)-approved consent forms and protocols. Each full-sized leukopak is produced from ~2 - 3x blood volumes using the Spectra Optia® Apheresis System, with acid-citrate-dextrose solution A (ACDA) as the anticoagulant. The collected product is then cryopreserved in a controlled-rate freezer. High-resolution HLA typing (Class I and Class II alleles and CMV status) are available upon request. Donor specifications (e.g. BMI category, smoking status, ethnicity, etc.) can be requested in the comment box above, after selecting from the product options. Donors are screened for HIV-1, HIV-2, hepatitis B, and hepatitis C.

Certain products are only available in select territories. Please contact your local sales representative or Product & Scientific Support at for further information.
