Anti-CD8A Antibody [Assigned #A11033]

This unconjugated rabbit monoclonal antibody targets the human CD8A protein, the alpha chain of the co-receptor that pairs with MHC class I molecules on cytotoxic T lymphocytes. Raised in rabbit and supplied as a 100 µl vial, it is intended for Western blot, immunohistochemistry, and immunofluorescence workflows in immunology research laboratories. The IgG isotype enables flexible pairing with secondary reagents across multiple detection platforms, and the unconjugated format permits direct fluorophore or enzyme conjugation for custom assays.

Researchers studying tumor-infiltrating lymphocytes, viral immunity, autoimmune pathology, and vaccine responses commonly use CD8A antibodies to identify and quantify cytotoxic T cell populations in tissue sections and cell preparations. Validated applications support diverse experimental contexts, including lymphoid organ phenotyping, immune checkpoint studies, and characterization of T cell subsets in patient-derived samples. The Antibodies.com offering provides a reproducible monoclonal reagent for human CD8A detection in research use only settings.
