CD8+ T cells, Negatively Selected (Human)

Cryopreserved vial (10 x 10^6 cells) of CD8+ T cells that were negatively selected from freshly isolated primary human peripheral blood mononuclear cells (PBMCs). The PBMCs came from a healthy donor, and were isolated from whole blood or leukapheresis samples using a Ficoll gradient. Magnetic antibodies to monocytes, granulocytes, CD4+ T cells, gamma/delta T cells and other immune subsets present in PBMCs were then used to purify untouched CD8+ T cells via immunomagnetic separation. Before and after CD8+ T cell isolation, the cells were stained to evaluate purity and viability by flow cytometry. Cells were cryopreserved in CryoStor CS10 cryopreservation medium (Stemcell, BPS-07930) at a controlled rate. Source: Normal human PBMC from Leukapheresis Sample.
