Lymphocyte isolation
(T cells, B cells, NK cells)

Improve consistency, efficiency, and quality with freshly collected immune cells

PBMC-Lymph-flowchart

One partner for sample collection and cell isolation

Patients donate whole blood in the comfort of their own homes. PBMCs = T cells, B cells, and/or NK cells are isolated within 24 hours of venipuncture collection, cryopreserved, and stored in liquid nitrogen.

Maximize results with flexible study size, design, and scope:

  • Procure PBMCs or plasma/serum concurrently with T cells
  • Specify inclusion/exclusion criteria (e.g., CLIA confirmed hepatitis B/C, HIV negative)
  • NGS Human Leukocyte Antigen (HLA) typing available
  • Multiple time points or event-based collection with recallable patient community (>90% study retention)
