|Application ||WB, IHC|
|Calculated MW||25729 Da|
|Other Names||T-cell surface glycoprotein CD8 alpha chain, T-lymphocyte differentiation antigen T8/Leu-2, CD8a, CD8A, MAL|
|Target/Specificity||A synthetic peptide corresponding to residues near the C-terminus of human CD8 Alpha chain was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||CD8 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains.|
|Cellular Location||Isoform 1: Cell membrane; Single-pass type I membrane protein|

The T cell coreceptor CD8 is a cell-surface glycoprotein expressed either as a disulfide-linked homodimer of two CD8 alpha monomers, or a heterodimer of CD8 alpha and CD8 beta. These receptors interact with ligands, such as major histocompatibility complex (MHC) class I, on the outside of the cell, with proteins inside the cell, such as the tyrosine kinase p56lck, and possibly with proteins on the same cell-surface (1). CD8 plays an important role in T cell development in the thymus and T cell activation in the periphery (2).
