The 341 antibody reacts with the β chain of the CD8 antigen on most thymocytes and a subpopulation of mature T lymphocytes (ie, MHC class I-restricted T cells, including most T suppressor/cytotoxic cells). The CD8 α and β chains (CD8a and CD8b, respectively) form a heterodimer on the surface of most thymocytes and thymus-dependent T suppressor/cytotoxic cells, whereas intestinal intraepithelial lymphocytes, many CD8+ T cells of athymic rats, many activated CD4+ T cells, and most NK cells express CD8a without CD8b. It has been suggested that the expression of the CD8a/CD8b heterodimer is restricted to thymus-derived T lymphocytes. CD8 is an antigen co-receptor on the T cell surface which interacts with MHC class I molecules on antigen-presenting cells. It participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck. Macrophages have also been reported to express CD8 α and β chains, which are involved in signal transduction. The 341 mAb blocks proliferative and cytotoxic in vitro responses of CD8+ effectors to allogeneic cells. Two-color analysis of the expression of CD8b on rat spleen cells. Lewis rat splenocytes were simultaneously stained with FITC-conjugated anti-rat CD8a mAb OX-8 (Cat. no. 554856) and biotinylated mAb 341 (Right panel ), followed by Streptavidin-PE (Cat. no. 554061). Note that the CD8a+CD8b- population represents NK cells. Flow cytometry was performed on a BD FACScan™ flow cytometry system.
