Anti-CD8 (human), Unconjugated Clone B-Z31 [Mouse]

Specificity: Recognises the T-cell coreceptor, a 32-34 kDa protein, Format: Phosphate-buffered saline with 1 % BSA and 0.09 % sodium azide, Working Dilution: Use 10 µl to label 106 cells or 100 µl of whole blood, Storage: Stable at +2-8°C for 12 months. For longer storage freeze aliquots, Application Notes: Suitable for Flow Cytometry, IHC Protein function: Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class I molecule:peptide complex. The antigens presented by class I peptides are derived from cytosolic proteins while class II derived from extracellular proteins. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. LCK then initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of cytotoxic T- lymphocytes (CTLs). This mechanism enables CTLs to recognize and eliminate infected cells and tumor cells. In NK-cells, the presence of CD8A homodimers at the cell surface provides a survival mechanism allowing conjugation and lysis of multiple target cells. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells. [The UniProt Consortium]
