Data Sheet

CD8+ Cytotoxic T Cells are isolated from mononuclear cells by positive selection using immunomagnetic cell separation procedures.


CD8+ Cytotoxic T Cells fulfill the role of regulating and/or carrying out the body’s immune response by eliminating intracellular pathogens such as viruses, and some bacteria and parasites. Upon recognition of an infected cell, the CD8+ T cell initiates apoptosis through the targeted release of effector proteins contained in granules within the T cell.

Most CD8+ Cytotoxic T cells express T‐cell receptors (TCRs) that can recognize a specific antigenic peptide bound to Class I MHC molecules (present on all nucleated cells) and a glycoprotein called CD8. The MHC molecule keeps the Cytotoxic T cell and the target cell bound closely together during antigen‐specific activation.
