Products
Normal human donor samples (blood, plasma, serum, leukopaks, PBMCs, isolated cells, bone marrow, cord blood)
Preclinical research-grade normal donor biological materials available in various formats (fresh and frozen), with optional expanded biomarker screening upon request.
Diseased human donor sample categories (autoimmune, cancer, viral infections)
Preclinical research-grade diseased human donor samples covering autoimmune disorders, various cancers and viral infection disease states available upon request.
Cancer PBMCs (cryopreserved)
Peripheral blood mononuclear cells isolated from cancer patients, purified by density gradient centrifugation and cryopreserved in cryopreservation media; supplied frozen. Donors tested negative for Hepatitis B, Hepatitis C and HIV 1 & 2; IRB consent indicated. Typical vial size: 1 million cells/vial.
Cancer BM-MNCs (cryopreserved)
Bone marrow mononuclear cells isolated from cancer patients (example: multiple myeloma), purified via density gradient centrifugation and provided in cryopreserved frozen format. Donors tested negative for specified infectious agents and IRB consent indicated. Typical vial size: 1 million cells/vial.
Cancer single-donor plasma
Whole-blood-derived single-donor plasma processed by centrifugation and frozen immediately after processing. Donors tested negative for Hepatitis B, Hepatitis C and HIV 1 & 2; IRB consent indicated. Typical vial size: 1 ml per vial.
Non-human primate primary cells
Primary cell products derived from non-human primates (examples include cynomolgus and rhesus) available for preclinical research.
