CD8 antibodies

CD8 antibodies

Clone: BW135/80
BW135/80 recognizes the human CD8 antigen which is strongly expressed on human cytotoxic T cells and thymocytes, and is also expressed on a subset of NK cells. The CD8 antigen is a disulfide-linked dimer that exists either as a CD8α homodimer or as a CD8α/β heterodimer. CD8 acts as a coreceptor for the T cell receptor and binds to the MHC Class I molecule. The CD8 antibody recognizes the α-subunit of the antigen.


Reagent can be used for immunophenotyping by flow cytometry. Abnormal numbers of cells expressing this antigen or aberrant expression levels of the antigen can be expected in some disease states. It is important to understand the normal expression pattern for this antigen and its relationship to expression of other relevant antigens in order to perform appropriate analysis.
Expression of CD8 may be used as aid to diagnostic in the characterization of samples from individuals suspected with hematologic neoplasia.
