Cryopreserved Human Peripheral Blood Mononuclear Cells (PBMC) are an invaluable resource for researchers investigating immune responses in vaccine development, drug discovery, cancer treatments, and many other fields involving Immune Monitoring.

Cells retain >90% viability upon thawing, with functionality comparable to freshly isolated PBMC. Donors are available in batches of up to 1200 vials of identical cellular material.

Cryopreserved, standardized batches of human PBMC purified from healthy leukapheresis donors are the ideal reference samples for ELISPOT and all Immune Monitoring applications.

Each donor is pre-tested for NK cytolytic activity and for antigen-specific T cell cytokine responses by measuring the secretion of IFN-γ, IL-2, IL-4, IL-5, and IL-17 in ELISPOT functionality testing.
