Clone 53-6-7
Isotype IgG2a
Characteristics The antibody detects: chain of the murine CD8 heterodimer, Mr 32-34 kDa
The 53-6.7 monoclonal antibody also blocks allogeneic help specific for class I MHC antigens and T cell responses to IL-2.
Purification Purified
Alternative Name CD8a/Ly-2 (CD8A Antibody Abstract)
Background In the mouse, CD8 exists in two forms: (i) a CD8 heterodimer composed of an chain (CD8/Lyt-2) and a chain (CD8/Lyt-3), and (ii) a homodimer of two chains. The heterodimer is found on the surface of essentially all thymocytes and the suppressor/cytotoxic subpopulation of mature T lymphocytes. Subsets of intestinal intraepithelial lymphocytes express CD8 without CD8. It has been suggested that CD8+- T cells mature extrathymically, while development of the CD8++ population of T cells is thymus-dependent. CD8 acts as a coreceptor with MHC Class I-restricted T cell receptors in antigen recognition and positive selection of MHC class I-restricted CD8+ T cells. In vivo and in vitro treatment with the 53-6.7 monoclonal antibody effectively depletes CD8+ cells.
Application Notes Working Dilution:

Representative data are included in this product insert.

Each laboratory should determine an optimum working titer for use in its particular application. Other applications have not been tested but use in such assays should not necessarily be excluded.
