|Clone Names||C8/468 + C8/144B|
|Other Names||T-cell surface glycoprotein CD8 alpha chain, T-lymphocyte differentiation antigen T8/Leu-2, CD8a, CD8A, MAL|
|Target/Specificity||Human CD8 recombinant protein (C8/468); A 13 amino acid peptide from C-terminal cytoplasmic domain of alpha chain of human CD8 molecule (C8/144B)|
|Application Note||Flow Cytometry : 0.5-1ug/million cells|
Immunofluorescence : 0.5-1.0 µg/ml
Western Blotting : 0.5-1.0 µg/ml
Immunoprecipitation : 0.5-1 µg/500ug protein lysate
Immunohistology (Frozen & Formalin-fixed) : 0.5-1.0 µg/ml for 30 minutes at RT
(Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes).
|Format||0.5 ml at 200ug/ml with BSA and azide|
|Storage||Store at 2 to 8°C.Antibody is stable for 24 months.|
|Precautions||CD8A (Cytotoxic- & Suppressor T-Cell Marker) Antibody - With BSA and Azide 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|

CD8 is a cell surface receptor expressed either as a heterodimer with the CD8 beta chain (CD8 alpha/beta) or as a homodimer (CD8 alpha/alpha). A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8a. CD8 binds to MHC class 1 and through its association with protein tyrosine kinase p56lck plays a role in T cell development and activation of mature T cells. For mature T-cells, CD4 and CD8 are mutually exclusive, so anti-CD8, generally used in conjunction with anti-CD4. It is a useful marker for distinguishing helper/inducer T-lymphocytes, and most peripheral T-cell lymphomas are CD4+/CD8-. Anaplastic large cell lymphoma is usually CD4+ and CD8-, and in T-lymphoblastic lymphoma/leukemia, CD4 and CD8 are often co-expressed. CD8 is also found in littoral cell angioma of the spleen.
