CD8 alpha in Canine PBMCs. CD8 alpha was detected in immersion fixed canine peripheral blood mononuclear cells (PBMCs) using Mouse Anti-Canine CD8 alpha alpha Monoclonal Antibody (Catalog # MAB6709) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell membrane. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

CD8 is a dimeric complex made up of two Ig superfamily members. The CD8 alpha chain is a 34 kDa type I transmembrane glycoprotein that is disulfide-linked either to itself forming CD8 alpha alpha, or to an unrelated 30‑35 kDa CD8 beta chain, forming CD8 alpha beta. CD8 alpha contains one V-type Ig-like domain in its extracellular region (ECD) that binds to class I MHC molecules. CD8 alpha beta is a TCR coreceptor, while CD8 alpha alpha promotes T cell survival and differentation. Within the ECD, canine CD8 alpha shares 63%, 45%, 43%, 68%, and 54% amino acid identity with human, mouse, rat, feline, and porcine CD8 alpha, respectively.
