Scientific Data Images for Mouse CD8 alpha Antibody

Detection of CD8a in Mouse spleen via seqIF™ staining on COMET™

CD8a was detected in perfusion fixed paraffin-embedded sections of mouse spleen using Rat Anti-Mouse CD8a, Monoclonal Antibody (Catalog #MAB11715) at 5ug/mL at 37 ° Celsius for 4 minutes. Before incubation with the primary antibody, tissue underwent an all-in-one dewaxing and antigen retrieval preprocessing using PreTreatment Module (PT Module) and Dewax and HIER Buffer H (pH 9; Epredia Catalog # TA-999-DHBH). Tissue was stained using the Alexa Fluor™ 647 Goat anti-Rat IgG Secondary Antibody at 1:200 at 37 ° Celsius for 2 minutes. (Yellow; Lunaphore Catalog # DR647RT) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the membrane. Protocol available in COMET™ Panel Builder.​

Detection of CD8 alpha in Mouse Spleen.

CD8 alpha was detected in perfusion fixed paraffin-embedded sections of mouse spleen using Rat Anti-Mouse CD8 alpha Monoclonal Antibody (Catalog # MAB11715) at 5 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using the HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane.

Detection of CD8 alpha in Mouse Thymus.

CD8 alpha was detected in perfusion fixed paraffin-embedded sections of mouse thymus using Rat Anti-Mouse CD8 alpha Monoclonal Antibody (Catalog # MAB11715) at 5 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using the HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane.

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).
