Overview +

All Sanguine study protocols and their resulting samples, which include all Sanguine at-home and apheresis collection programs, are conducted under an Institutional Review Board (IRB). Sanguine operates under an electronic informed consent process which executes 21 CFR part 11 compliant e-signatures, and Sanguine systems interacting with study participant information are HIPAA-compliant.

Sanguine’s LeukoLot™ bulk PBMCs provide researchers with high-yield (billions of cells per donor), high-viability peripheral blood mononuclear cells (PBMCs) collected from a leukopak and isolated within one day to ensure optimal functionality. After the cells are isolated, washed and counted, PBMCs are aliquoted and stored using CryoStor® CS10 freezing media. Bulk PBMCs include donor demographics, verified-conditions via donor electronic medical records, and infectious disease testing.Our bulk PBMCs contain a diverse population of immune cells, including T cells, B cells, NK cells, monocytes, and dendritic cells—making them ideal for immunology research, drug development, and cell-based assays.

Well-characterized PBMCs for alpha-gal syndrome (AGS) research supports studies on immune response, allergic mechanisms, and therapeutic development to advance understanding and treatments for this tick-borne meat allergy.

Infectious disease testing requirements differ globally. If you are ordering from outside the U.S., please reach out at to confirm that we can meet your country’s regulatory and documentation needs.
