Leukopaks and LeukoLots™: Healthy and Disease State
High-quality, RUO apheresis products
from our diverse network of research-ready donors
Leukopaks: One Donor, Billions of White Blood Cells
Large volumes of white blood cells can be separated by apheresis (leukapheresis) while plasma and red blood cells are returned to the donor. Research Use Only (RUO) leukapheresis products collected from the same donor provide a reliable and consistent source of up to 10 billion immune cells, including peripheral blood mononuclear cells (PBMCs), and rare cells, as well as for biomarker discovery, immunology, autologous, and allogeneic cell therapy research and product development.
LeukoLots™ are isolated PBMCs from a leukopak that are aliquoted and cryopreserved. Screening vials are available to ensure you choose the right LeukoLot for your research needs.
