Peripheral Blood Mononuclear Cells (PBMCs)

A white tube labeled

Human Peripheral Blood Mononuclear Cells (PBMCs)

Peripheral blood mononuclear cells (PBMCs) are nucleated cells (monocytes, lymphocytes, dendritic cells, and progenitor cells) collected from peripheral blood by density gradient centrifugation.

All PBMCs come with a Certificate of Analysis, limited donor information, flow profile, and microscopic observations. PBMCs from TRIMA filters are subject to limited donor information and cannot be used for whole genome sequencing.

All cells are obtained using Institutional Review Board (IRB) approved consent forms and protocols.

PBMC are from apheresis product by density gradient centrifugation. Fresh, frozen, and fresh frozen are available. Final cell concentration, cryopreservation medium, and custom flow panels may all be requested here.

If you are interested in PBMC from whole blood or LRS chamber, you request starting material at time of order.

Donors are infectious disease tested annually and are free of Hepatitis B, Hepatitis C, HIV-1, and HIV-2. For more information, please contact us.

All cells are obtained using Institutional Review Board (IRB) approved consent forms and protocols and standard phlebotomy practices.
