Human Primary Cells*
Access high-quality, ethically sourced cells with flexible delivery options.
Featured: Diseased Leukopaks*
Start your research confidently with a reliable supply of peripheral blood (PB) leukopaks from donors diagnosed with autoimmune or metabolic diseases.
Leukopaks*
Get large numbers of fresh or frozen single-donor peripheral blood mononuclear cells (PBMCs) in a selection of leukopak sizes.
Cancer Blood Products*
Choose ethically sourced peripheral blood (PB) products from donors diagnosed with a specific solid tumor or hematological cancer.
Peripheral Blood Mononuclear Cells*
Obtain normal or diseased PBMCs from a large donor pool in convenient sizes for your research. Large quantities are reservable to ensure consistency across your experiments.
NK Cells*
Begin experiments by using isolated fresh or frozen natural killer (NK) cells and eliminate the need to perform downstream cell isolation.
*Certain products are only available in select territories. Please contact your Sales representative or the Product & Scientific Support team at techsupport@stemcell.com for further information.
