Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
CD8 alpha is a cell-surface glycoprotein expressed on many cytotoxic T lymphocytes and functions as a coreceptor with the T-cell receptor during recognition of antigen presented by MHC class I molecules. CD8A can form alpha-alpha homodimers or alpha-beta heterodimers with CD8B.
CD8A / CD8 alpha is commonly studied in cytotoxic T-cell biology, T-cell phenotyping, antigen recognition, MHC class I responses and immune-oncology research.
