CD8 Antibody

The CD8 antigen is expressed on human cytotoxic/suppressor T-cells, human NK cell subset, and a cortical thymocyte subset. CD8 is a co-receptor molecule binding to MHC class I. The functional co-receptor is either a homodimer of alpha chains or a heterodimer of alpha and beta chains. The antibody can be used for detecting CD8 alpha in ELISA, western blot and immunohistocytology with paraffin-embedded tissue sections.
