Cell Isolation & Cryopreservation

PBMC Banking

Xeno Diagnostics’ donor program provides both a number of different donors as well as a number of donors who can be used for longer term studies. All donors have been consented through our institutional review board program. By maintaining our own donor pool, we can perform assays using either fresh or cryopreserved cells.
Besides humans, XD has isolated PBMCs from baboons, cows, cynomolgus macaques, pigs, goats, dogs, cats, and rats. Animal specimens are processed less than 24 hours from blood draw and are cryopreserved in our state-of-the-art storage facilities. Our storage facilities are temperature controlled and monitored 24/7 with emergency power backups and redundant equipment for specimens stored at +4oC, -20oC, -80oC, and liquid nitrogen.

Cryopreservation Capabilities

Whole blood specimens can be shipped to Xeno Diagnostics for PBMC isolation and cryopreservation. Frozen cells can be maintained at XD or shipped back to your facility using LN2 dry shippers or on dry ice.

Other Cell Isolations

In addition to the PBMC isolations, human and cynomolgus macaque cell subsets to include CD3, CD4, CD8, and monocytes can be isolated and phenotypically confirmed by flow cytometry for immediate use or cryopreserved for future use.
