T-cell activation is an essential step in the immune response. CD8-positive T cells play a key mediator of adaptive immunity. CD 8 T cells are MHC class I-restricted T cell that include cytotoxic T cells which are important for killing antigen-specific tumor cells or virally infected cells, and CD8-positive suppressor T cells which restrain certain types of immune response.
Human Peripheral Blood CD8 T Cells are isolated from human PBMCs of a single donor and cryopreserved immediately. Human CD8 T cells contain subset of Cytotoxic T Cells, CD8-positive suppressor T cells.
The purity of CD8 positive cells is >90 %.
