Start immuno-oncology experiments confidently with a reliable supply of ethically sourced, fresh and frozen peripheral blood products from donors diagnosed with colorectal cancer. Options include cancer-sourced whole blood, one-tenth leukopaks, frozen peripheral blood mononuclear cells (MNCs or PBMCs), and custom-isolated frozen products such as plasma and serum. We help you get the cells you need with personalized service and flexible delivery times.

Cancer-sourced leukopaks are an enriched leukapheresis product consisting of a large number of single-donor MNCs. Primary human MNCs are isolated from peripheral blood, leukapheresis, or whole blood samples using density gradient separation or red blood cell lysis and cryopreserved in animal component-free CryoStor® CS10 medium. All fresh and frozen peripheral blood products are obtained from donors diagnosed with colorectal cancer using Institutional Review Board (IRB)-approved consent forms and protocols. Additional documentation to meet institutional requirements is available upon request. Sodium heparin (Na-Hep), ethylenediaminetetraacetic acid (EDTA), or acid-citrate-dextrose solution A (ACDA) is added during collection as an anticoagulant.

Contact techsupport@stemcell.com if high-resolution HLA typing (Class I and Class II alleles and CMV status) is required or for donor specifications (BMI category, smoking status, ethnicity, etc.). Donors are screened for HIV-1, HIV-2, hepatitis B, and hepatitis C. Certain products are only available in select territories.
