CD8 alpha in Mouse Splenocytes.
CD8 alpha was detected in immersion fixed mouse splenocytes using Rat Anti-Mouse CD8 alpha Alexa Fluor® 488‑conjugated Monoclonal Antibody (Catalog # FAB116G, green) at 10 µg/mL for 3 hours at room temperature. Cells were counterstained with DAPI (blue). Specific staining was localized to cell surfaces.

Background: CD8
CD8, also known as Ly-2, is a heterodimeric glycoprotein consisting of an alpha and beta chain. It is expressed on cytolytic T cells and functions in conjunction with the T cell receptor in the recognition of MHC/peptide complexes. Mouse CD8 (containing an alpha/Ly-2 or alpha′/Lyt-2 chain) is an antigen co‑receptor on the T cell surface which interacts with MHC I molecules on antigen presenting cells (1). CD8 alpha beta heterodimer is expressed on a subpopulation of mature T cells (2, 3). CD8 alpha, without CD8 beta, has been detected on subsets of gamma delta TCR-bearing T cells (4), intestinal intrathymic lymphocytes (5, 6) and dendritic cells (7, 8).
