Specificity

Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.

Cells were incubated with an excess of purified unconjugated CD8 (BW135/80) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Sensitivity

Performance comparison
Selected fluorochrome conjugated antibodies from Miltenyi Biotec were compared to commercially available hybridoma clones in flow cytometry analysis.

Flow cytometric comparison of different clones for CD8. Human peripheral blood mononuclear cells (PBMCs) were stained with CD8 antibodies and with a suitable counterstaining. As a control, CD8 antibody staining was omitted and cells were measured in the same channels. Flow cytometry was performed with the MACSQuant® Analyzer. Cell debris, dead cells, and cell doublets were excluded from the analysis based on scatter signals and 4',6-diamidino-2-phenylindole (DAPI) fluorescence. No FcR Blocking Reagent was used. The recommended titers of respective antibodies from different suppliers were used.

Specifications for CD8 Antibody, anti-human

Overview

The monoclonal antibody 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 co-receptor for the T cell receptor and binds to the MHC class I molecule. The CD8 antibody recognizes the α-subunit of the antigen.
