Sanguine’s LeukoLot™ RUO peripheral blood mononuclear cells (PBMCs) are isolated, aliquoted, and cryopreserved from a leukopak collection. These collections of PBMCs are collected from healthy donors and over 50 IRB-approved conditions for apheresis collection. Before committing to an entire lot, you can screen up to 10 donors at a time to identify the PBMC composition that best fits your research needs.
