T-cell activation is an essential step in the immune response. CD8+ T cells play a key mediator role of adaptive immunity. CD8+ T cells are MHC class I-restricted T cells including cytotoxic T cells which are important for killing antigen-specific tumor cells or virally infected cells, and CD8+ 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+ suppressor T cells.
The purity of CD8+ positive cells is >90 %.
